working principle of fish feed dryer machine

—— RICHI MACHINERY ——

The belt circulating feed dryer is mainly composed of supporting feet, feeding section, drying section, returning section, conveyor belt, spreader and other parts.

Principle: After the air is heated by the heat exchanger inside the dryer, it is driven by the circulating fan to enter the fish feed dryer equipment. After the drying medium and the material exchange heat and moisture on the conveyor belt, part of the air is discharged through the common air duct, and the other part of the air is reheated by the heat exchanger, and the mixed fresh air enters the fish feed drying machine again.

The material is evenly spread on the conveyor belt through the spreader, and enters the fish shrimp feed dryer machine with the conveyor belt. After drying once, it is turned back in the return section, and enters the lower conveyor belt for secondary drying or multiple drying, and then discharged.

The fish feed dryer machine can improve the stability of the feed and prolong the shelf life of the product; promote the change of the physical properties of the pellet feed (such as hardness, taste and density, etc.); reduce the viscosity of the material and facilitate the processing of subsequent procedures; reduce the moisture content; prevent Growth of microorganisms and production of toxins.

Typical process of fish feed dryer machine

Advanced process design, reasonable fish feed dryer selection and perfect auxiliary configuration are the prerequisites to ensure the quality of dried particles.

01 Feeding

The extruded high-temperature pellet feed can enter the spreader of the dryer by means of belt conveyor + chute or pneumatic conveying, and evenly distribute it in the machine.

02 Discharge

The dried pellet feed is discharged from the fish feed dryer machine outlet, and can be collected into the discharge cone first in the process configuration, and then enters the next process through the belt conveyor.

03 Dust collection system

In the actual process design, in addition to shortening the length of the air duct as much as possible, rock wool should be wrapped outside the pipe for thermal insulation, and the entire pipeline should be well sealed to avoid loss of air volume. The size of the matching brake dragon should be appropriate. If it is too large, the centrifugal force will not be large enough to blow out the dust. If it is too small, it will not keep the air flowing and the dust will be blown out.

Operating tips of fish feed dryer equipment

01 Drying time

The conveyor belt is driven by a variable frequency motor, and the frequency of the motor can be adjusted to easily control the drying time of the pellet feed. Generally, the drying time depends on the physical properties of the pelleted feed (sinkable or floating), such as the moisture content, size, shape and density of the pelleted feed after extrusion.

The upper and lower feed layers need to be controlled separately. Since the pellet feed moisture is high when entering the fish feed dryer machine, the feeding speed of the feed layer should be faster when setting, so that the pellet feed material layer is thin and the penetration of hot air is good, ensuring the moisture content of the pellet feed just entering the machine. The speed of the lower material layer is relatively slow, and the material layer is relatively thick to ensure sufficient drying time.

It should be noted that although according to experience, a long drying time is always good, but the frequency of the motor is too slow, which will cause the material layer on the conveyor belt to be too thick, which will make it difficult for the hot air to pass through the material and affect the drying effect. In actual fish feed dryer machine operation, it is recommended that the thickness of the material layer should not be greater than 10cm.

02 Drying temperature

The control of the fish feed dryer machine drying temperature is directly related to the energy consumption and operating cost of the steam supply system. The adjustment of the drying temperature also depends on the physical properties of the pellet feed (sinkable material or floating material). At the beginning of debugging, it can be adjusted according to the allowable product of the product.

The maximum temperature is carried out. After a certain operating experience, the temperature of the fish feed drying machine can be reduced as much as possible on the premise of ensuring the quality of the product. Fish aquatic feed dryer machine operators need to record the production operation of each shift and find out the best operating parameters for their own products.

03 Hot air flow of fish feed dryer machine

There are many air ducts and dampers on the inside and outside of the dryer, and the equipment has been pre-set before leaving the fish feed dryer factory. Balanced airflow is very important for product quality. When drying, the size of the circulating air flow on both sides will directly affect the uniformity of the moisture content of the pellet feed on the bandwidth. In actual fish feed dryingmachine operation, it is required that the difference in the final moisture content should not exceed 2% to 3%.

In actual fish feed dryer equipment production, it is necessary to adjust the size of the dampers on both sides according to the characteristics of the specific pellet feed. For small-sized pellet feed, its opening can be appropriately reduced to avoid blowing the material out of the conveyor belt. The control of the size of the moisture exhaust damper also affects the final moisture content of the pellet feed. The moisture exhaust damper close to the feeding section needs to be opened to ensure that the moisture is taken away by the auxiliary air net in time.

04 Distribution of materials in the conveying bandwidth

Inside the belt fish feed dryer machine, the material layer of the cross-section in the same width direction should keep the same thickness as much as possible, otherwise there will be differences in moisture. The adjustment of the feed spreader is the key. In addition, attention should be paid to the size of the hot air flow on both sides of the dryer. If the air flow on one side is too large, the material will be blown to the middle, resulting in a hump phenomenon.

In a word, the drying process is a complex heat and mass transfer process, and it is also a small systematic project. Only by comprehensively adjusting various parameters can the advantages of the equipment be maximized and the maximum profit and economic benefit can be created for the compound feed mills.

RICHI horizontal belt series feed dryers have been widely used in the production of aquatic feed and pet food since they were put into the market, and have been recognized by the majority of users for their energy-saving and high-efficiency features.

In the future, Richi Machinery will continue to actively explore the development trend of the industry, and in combination with the actual needs of our customers, continue to innovate, create energy-saving and efficient fish feed dryer equipment and environmentally friendly smart compound feed factories, and provide stronger support for feed processing and production.

Faqs of fish feed dryer machine operation

01 High energy consumption of drying steam

Increase the drying time, drying wind speed, and stabilize the air path. Only when they play a synergistic role can the drying temperature be effectively reduced.

02 High power consumption for drying

Short drying the effective air path route (to prevent the phenomenon of South-to-North water transfer) and removing unnecessary wind resistance will definitely reduce the kinetic energy (impeller) of the drying circulation air path.

03 The drying air path is unreasonable (the material is blown off)

Whether the drying air path is reasonable mainly depends on the fish feed dryer machine design engineer and whether the designed air path can be realized according to the design.

04 Uneven drying moisture

The uniformity of drying moisture mainly reflects the deviation and stability of the designed air path in actual operation, and the uniformity of the cloth of the distributor.

05 Difficult to dry

The difficulty of drying mainly reflects the sinking extruded material, the extruded floating material above 20mm, and the floating extruded material below 0.8mm.
