The difference between wet expansion and dry expansion is that the raw materials are prepared in advance before expansion, and the temperature is increased by steam or water. The so-called conditioning refers to the hot and wet effect of steam on pet food raw materials, so that the starch in the raw materials is pre gelatinized, the protein is denatured and the raw materials are softened, which is conducive to improving the expansion granulation effect and expansion quality of dog food.

Aquaculture has always been an important part of national agriculture. It depends on mountains and rivers. For the majority of farmers close to the water area, aquaculture fish and shrimp is a realistic and feasible method and way for them to obtain economic benefits.

Extrusion technology is a commonly used technology in modern feed processing. After the feed is processed by extruding technology, it can make starch gelatinization and degradation, protein denaturation, reduce anti-nutritional factors, increase palatability and many other advantages in the feed; but there are also unfavorable factors such as generating indigestible substances, destroying vitamins, and increasing costs.

- single screw extruder: suitable for processing all kinds of raw materials and ordinary livestock and poultry compound feed - twin screw extruder: the final product requires good molding and beautiful appearance, compound feed (aquatic products, pet food) with uniform maturity and adjustable density, and raw materials with high added value（ ɑ Starch, tissue protein, etc It should be noted that the above division is not absolute. For example, we recommend using twin-screw to produce aquatic feed, but at present, many enterprises use single screw to produce aquatic feed. Many articles have introduced their application in aquatic products

More and more fast food products on the market have come into view, and self-heating rice has been in the limelight in the past two years. It has a glutinous taste, full of fragrance, convenient and ready-to-eat, and nutritionally comparable to ordinary rice, quickly occupying people's taste buds.

Turn on the power supply and test the operation · Check the lubrication system. Start the "oil pump" start button (green), if there is oil in the oil pump overflow pipe, the oil pump will turn down, otherwise it will reverse.
