Power in motion – New KubexTM pellet mill The new Kubex™ T pellet mill takes the successful foundation of the popular Kubex™ to a new dimension, continuing the tradition of robustness, reliability and ease of operation of the previous model, but driving it to an even more efficient and powerful level. Up to 30 %1 less energy consumption, high production capacities of up to 80 t/h2 and a customer driven design are the result of extensive research and development by Bühler in cooperation with leading feed millers.

Direct drive sets new standard in energy efficiency A for a long time awaited drive concept has now become reality: without gearbox and transmission belts, the machine’s direct drive significantly reduces maintenance requirements and increases the pellet mill’s uptime. Thanks to efficient power transmission, the new Kubex™ T saves up to 30 % 1 energy per ton of produced pellets compared to conventional drive systems. Another advantage is the variable die speed that is adjustable during operation. The flexibility provided by this feature enables on-‐going optimization of the production process and the pellet quality based on the feed formulation, and also extends the lifetime of the die.

High performance, small footprint The new Kubex™ T pellet mill is available in two versions, with Kubex™ T12 being the most powerful model with power of up to 585 kW and 1200 mm die diameter, delivering high pelleting performance of up to 80 tons/hour 2. The smaller version Kubex™ T9 comes with motor power of up to 410 kW and a 900 mm die,

suitable for production capacities of up to 50 t/h 2. Characterized by its very compact design, the new Kubex™ T pellet mill fits the exact space requirements of every feed mill due to its small footprint in length, width and especially height. In existing feed mills, line capacity expansion is made possible without costly building and process modification works.

Customer driven design Bühler innovators have worked closely with leading feed producers to ensure the Kubex™ T pellet mill fulfils the aspirations of feed millers for hygienic, ergonomic and robust machine design. Wide- opening, smooth-running sliding doors on both sides provide full access to the machine for fast and easy maintenance, while the slightly pressurized machine housing efficiently prevents dust settlements in critical areas. An improved die change concept with access to the screws and fittings from the clean motor chamber significantly reduces the time needed for the die change, maximizing machine uptime. Another new development is the ABS control for the press rolls, preventing roll slippage and thus protecting the machine against blockages and equipment damage.

Power forward Quite simply, selecting Bühler as a partner means gaining access to the best technology and process expertise in the feed milling industry. Close collaboration with customers is always aimed at increasing their productivity and competitiveness. Bühler is continually empowering feed

Practical ways to improve feed conditioning efficiency By Zhou Xiang, Ye Zhen, Jiangsu Muyang Group Co., Ltd, China

The primary purpose of conditioning is to improve pellet quality and pellet mill throughput. If being correctly operated and controlled, a given conditioner could be optimized to achieve the best quality at the best production rate possible for a pelleting system. According to the report of Energy Intensity of Agriculture and Food System published on July 29, 2011, feed provision contributes, on average, 75% of energy inputs to livestock production in U.K, about 86% for feedlot beef production in the United States, and about 90% of cradle-to-farm gate energy use for salmon produced globally. Sourcing energy-efficient feed inputs therefore offers considerable opportunity to decrease energy use in farming industries. Under this trend, only processes, systems and equipment that saving energy in feed production can help feed manufacturers keep competitive in the market. Conditioning is one of the most important processing steps in pellet feed production. How to cut energy usage and improve processing efficiency of a conditioner has been the question that feed manufacturers always concerned. We at Muyang have studied the possible ways to solve this question for years. In this article, we will introduced some practical ways to improve feed conditioning efficiency through carefully controls on conditioning temperature, retention time and water addition in production.

Conditioning temperature Moisture, heat, and pressure combine to gelatinize or break down protein components in the feed ingredients during conditioning, which permits better digestibility and durability for feed pellets. Table 1 shows the effects of conditioning temperature on pelleting performance. As feed mash temperature increased in conditioning stage, the durability of pellet products is improved while the energy used for producing per ton of feed is reduced. A great deal of heat contributes to easy penetration of steam into feed mash molecules, forming hydration water, which binding with ingredients will make feed mash more pelletable.

However, not all materials are adapted to the above mentioned “feed mash temperature and pelleting performance” rule. For feed mash of heat sensitive ingredients such as whey, milk, urea, etc., conditioning temperature that higher than their gelatinization temperature or solution temperature (usually is about 60°c) will cause over-gelatinized or too much water in feed mash, resulting in blockage in die holes. While for cereals Table 1: Effects of conditioning temperature on palleting Mash Temp/°C

and materials of high protein content, a conditioning temperature that higher than 85°c can be able to increase the plasticity, cohesiveness and pellet ability of feed mash. Therefore, conditioning temperature is formulation dependent. It should be controlled properly to achieve good conditioning.

Retention time The time available for heat and moisture to penetrate into the core of each particle before pelleting is referred to as “retention time”. It is limited and supposed to be less than the time needed for a given particle to move through the conditioning chamber, because feed mash doesn’t contact with steam in the distance between feeding inlet and steam inlet. However, retention time cannot be measured precisely and, in reality, it represents the average amount of time mash retaining in the chamber. To optimize conditioning operations, retention time must be optimized. Trails were carried out in a feed mill in Guangdong Province of China to study the impacting factors and find out practical methods to optimize conditioning retention time. The first trail was set up to evaluate the influence of paddle angle on conditioning performance. It was subjected to 4 paddle settings giving:

• Setting 1: all paddles are forward ones (retained at ex-works setting) (Fig.1-a)

• Setting 2: with 4 backward paddles (Fig.1-b);

Feed Pellet Press Productivity Influencing Factors By Amanda Zhou, Allance Machinery, China, Email: info@pellet-machine.net

Feed pellet press is to produce pellets for poultry, livestock and aquacultural animals. The main raw materials for feed pellet press are crushed or milled corn, bean cakes, straw, grass, rice husk, etc. Feed pellet press can be divided into three types which are ring die feed pellet press, flat die pellet mill and double roller feed pellet press. However, due to pellet press manufacturing technology and missoperation, feed pellets productivity can hardly satisfy the expected requirement; besides, the feed pellets surface is rough, fragile and high powder rate. We will analyze the factors, which influence feed pellet press productivity.

of ring die and roller will be increased and make it hard to pelletizing. For pellet press with little die holes, it is harder to form pellets; whatâ&#x20AC;&#x2122;s more, the material will have

1. Raw materials Raw materials play the direct role in feed pellet production. Different raw material component, milling condition and the mixing rate can exert great influence on feed pellets. 1.1 Material components Materials with high starch content are easy to be gelatinized and sticky enough to form feed pellets after conditioning. For those materials with high crude fiber content, a certain amount of fat addition can reduce friction between raw materials and ring die during pelletizing, and is good to form smooth feed pellets. The common fat addition amount is about 1% for more addition will make pellet loose. If more fat is needed, we can consider spraying fat after pelletizing, which is especially suitable to, high standard feed pellets production. 1.2 Milling granularity Grain material milling granularity decides feed pellet surface area which means the finer granularity, the larger size, the faster speed of moisture absorption; then it is easy for feed material conditioning and pelletizing. From the perspective of pelletizing, the finer material, the higher pelletizing strength; but more steam will block pellet press. Besides, the finer material will consume more powder. If the materials are too crude, the wear

bad gelatinization, low productivity and high powder rate in feed pellets. Therefore, for the common poultry and livestock feed pellets, corn milling should adopt 2.53.0mm sieving plates which can avoid too finess and ensure feed granularity for conditioning for less powder content. 1.3 Grain material mixing The evenness of grain material mixing should be paid attention as well. Because of the complexity of feed formula, the huge differences of different materials, we should choose the right mixing time according to the formulas with the aim of controlling the variable coefficient of evenness to 5% and laying a good foundation for pelletizing.

3. Feeding flow control Feeding flow control is to ensure pellet press work continuously and uniformly and thus quite important. Feeder part should be unobstructed for smooth feeding. Take SZLH series 400 as an example, the feeding flow should be no less than 10t/h. In order to make the even feeding flow, it is wise to install a surge bunker on top of feed press. It is difficult to ensure even feed flow without a surge bunker or other connecting pipes (longer than 0.5m). In a general way, when feed pellet press works stably, steam supplies adequately, all feeding gates open, feeding speed is the rated value but the main motor can never achieve the rated power value, we can judge that the feeding flow is insufficient. 4.Pelletizing operation 4.1 Adjust the space between roller and die. Too small space between roller and die will make easier to create wear and loud noise; too big space will influence material pressing; thus the space is about 0.05- 0.30mm. Sometimes a feeler gauge is good to help. 2. Steam quality control Using steam for feed pellets can improve pellet press production and pellet quality. Steam is the source of both moisture addition for conditioning and starch gelatinization. Adding a certain amount of steam in conditioner can kill some bacteria and also dilute the natural binder in feed materials; in this way, the particles surface forms a layer of thin water-bearing stratum which is in favor of gelatinization and pelletizing. The correct design of steam pipe should ensure not only pressure and flow but also prevent condensate water entering conditioner. Generally, raw material moisture content is about 12% before conditioning, steam pressure is high and moisture content is low; while after conditioning, moisture content is above 16.5% and pellets are difficult to store. The conditioning temperature is 85Â°c for common animal feed pellets; but change it lower or higher in winter and summer respectively.

4.2 Industrial butter is needed Butter is needed on roller so that bearings can be protected safely from high temperature. 4.3 Feeding knives adjustment Adjust feeding knives in case materials canâ&#x20AC;&#x2122;t enter the space between roller and die. Part of raw materials will go out of die holes and form more powder; thus the adjustment should make sure the space between the curves on the upper edge and die is 2-3mm. 4.4 Feed pelletizing Start pellet press, conditioner and feeder successively; at this time, feeder should be in the smallest feeding amount. In order to avoid sundries enter to the die, the operator should open the discharge door outside pellet press for removing impure materials. When the materials are clean, we can lead them to ring die. The important thing is that we should feed part of the material to see if there are feed pellets formed. If everything works

Global Milling Advances Page 12

well, we can increase raw material and steam to the rated current. If the materials enter pressing chamber but no feed pellets forming, with the electric current increasing; we should open discharge door outside pellet press and watch if the electric current lowers down. Mechanically, the pelletizing process involves forcing soft feed through holes in a metal ring die or flat die. The holes may be round or square, tapered or nontapered. This is done either by using locally fabricated pelleting machine, which is operated by diesel engine, electricity powered machine or manually, or by using automatic highly sophisticated machines with hot air or water conditioning. It consists basically of cylindrical dies of different diameters to pelletize varying sizes of feed, which depends on the age, size and species of animals involved. Most feed produced is a compressed pellet.

Pelleted feed has numerous advantages which include less feed wastage, uniform feed intake, and destruction of growth inhibitors. It is noteworthy that at the beginning stage of feeding, we should not add steam anxiously. Because at this time, raw materials are in small amount and the steam amount is hard to control. More steam and less material is easy to block pellet press. Besides, before close down pellet press, we should add some oil material to ring die holes to prevent materials becoming hard. Feed pellet production is simple but good feed pellet is not so easy because it needs not only pelletizing technology but also rich experience. We hope this analysis will assist you in improving feed pellet productivity to some extent. For both domestic and commercial feed pellet production, we can customize the most cost-effective pelletizing solutions.
