Equipment introduction
The thawing machine is composed of a frame, a three-layer meshbelt, a built-in mixed gas pipe, a Roots blower, a built-in injectionpipe, a PLC control cabinet, and an RV reducer. The steam outputcan be controlled separately; the cold air circulation is in the internalcirculation mode, and the compressed air of the blower is in theinternal circulation mode; PLC can set menus such as: menu 1 bulkduck wings, menu 2 duck necks, etc. to realize one-key start andonline adjustment.
The material enters a mesh belt of the thawing machine, and thespray tube is blown up and down, and acts on the surface of theproduct at a speed of about 3 meters per second. Since thetemperature of the product is minus 18o and the surface is an icelayer, the spraying gas can be appropriately increased. Thetemperature causes the surface of the product to frost, and the solidice between the objects loosens. When falling into the second floor,the material will be scattered by the drop. During the operation of thesecond floor, the temperature of the jet gas can be appropriatelylowered and will be dispersed. The product is frosted at thedisconnected interface, which exposes the internal flesh andproduces condensed water when the product runs at the end of thesecond layer. The temperature of the sprayed gas on the third-layermesh belt is lowered, and combined with the internal cold aircirculation of the built-in air cooler, the use of similar, Defrosting ata relatively low temperature to prevent overheating and discolorationof the product surface. The entire thawing process takes about 30minutes, and adjustments can be made according to differentproducts.
