Wet Type Fish Feed Machine

Wet Type Fish Feed Extruder Machine Introduction
As the major part of fish feed production plant, wet type fish feed extruder is equipped with a boiler which can continuously providing hot steam. It can produce all kinds of floating or sinking aqua feed for fish, eel, shrimp, crab, loach, bullfrog, etc, and can produce many kinds of pet feeds for cat, dog, and etc. The pellet size can be from 0.9-15mm to feed different size fishes. High capacity and top quality products, Wet type Sinking and Floating Fish Feed Extruder is a preferred choice for medium or large size feed processing factory and aquaculture farm.

Advantages of Floating Fish Feed Extruder
◆ Feeding evenly and constantly: Flat-bottomed scraper mechanism and feeder controlled by transducer make sure that the materials can be fed evenly and constantly.
◆ High efficiency and low power consumption: With conditioner, the steam and water can be directly injected into the extruding chamber through special mechanism, thus the quality and quantity of products can be improved greatly with lower power consumption.
◆ Cutting quickly and accurately: Removable cutting mechanism use knives with good elasticity, which attach to the die plate tenderly and can be regulated in six directions, can be operated quickly and accurately.
◆ Wide application: Variably configurations of screw bolts can match the producing demands for different formulas and raw materials.
◆ Longer service life: Screw bolts and dies are processed through vacuum quench treatment, also be processed with high processing precision and have a long using longevity.
◆ Easy operation: All the operating parts like steam valves, etc, adopt the humanization design, in order to facilitate actual operations.

Superiorities of Wet Type Fish Feed Extruder Conditioner
▶ Screw sleeve adopts jacketed construction, which can be injected in with hot steam or cooling water, thus the extruding temperature can be controlled effectively.
▶ The conditioner can make the materials have fully gelatinization of starch by a combination of hot steam and mechanical shear/mixing. The materials may remain in the conditioner for a time over 180s.

Classification of Fish Feed Extruder
The Fish Feed Pellet Extruder can be divided into two types: Dry type fish feed extruder and Wet type extruder. The differences and features of the dry type and wet type extruder:
1. Dry type fish feed extruder does not need the steam boiler while the wet type is with the conditioner and need to equip the steam boiler. So the dry type fish feed pellet machine is cheaper and easier to use and operate.
2. The feed pellet made by wet type fish feed pellet machine is more smooth and with better quality because the material is ripen and mixed enough in the conditioner compared with the dry type extruder.
3. The capacity of the wet type is higher than the dry type feed pellet machine, so usually the wet type fish feed machine is suitable for large feed pellet factory while the dry type fish feed pellet machine is better and economic for the small and medium size user or factory.

Fish Feed Pellets: To Sink or to Float?

Commercial fish diets can be classified into floating (extruded) or traditional sinking (pressure-pelleted) pellets. Both floating and sinking feed can produce satisfactory growth, but some fish species prefer floating, others sinking. There are both pros and cons both in the two types of pellets. However, the use of floating pellets provides more advantages compared to sinking ones:
1. Reduce Waste.
Sinking pellets that remain at the bottom of the tank will often get lost and wasted. However, the floating feed pellets can retain its shape, even after being in the water for many hours, uneaten feed are still intact.
2. Decrease Disease.
Sinking pellets that remain at the bottom of the tank will eventually rot, which may give rise to proliferation of bacteria and spreading of harmful fish disease.
3. Convenient Observation.
Another reason to feed floating (extruded) pellets because the farmers can directly observe the feeding intensity of his fish and adjust feeding rates accordingly. Determining whether feeding rates are too low or too high is important in maximizing fish growth and feed use efficiency. However, sinking pellets will fall into the bottom of the tank, even fish can not find them.
