Quick Freezer cold storage will be a new direction for the development of cold storage in my country
2022-11-24
Quick-freezing cold storage, also known as fast cold storage equipment, is more and more valued by the cold storage industry for its advantages such as fast freezing speed, small equipment size, low investment cost, no corrosion, and strong complete set. More and more users are beginning to transform into fast cold storage equipment, so fast cold storage equipment will be the future development direction of the cold storage industry.
Fast cold storage equipment is not a device that has only been developed in recent years. Fast cold storage equipment has been in use a few years ago, but it is widely used by users. The current quick-freezing warehouses include air-cooled quick-freezing warehouses, spiral quick-freezing warehouses, tunnel quick-freezing warehouses, flat-plate quick-freezing, liquefaction quick-freezing devices and liquid nitrogen quick-freezing. CBFI can provide you with solutions for the first three.
1. Air Cooler Quick freezer
The cooling fan is used as the cooling device to blow the cold air onto the cooled goods, forcing the cold air in the warehouse to circulate, so as to achieve the cooling effect and freeze the goods well.
2. Spiral Quick Freezer
The spiral freezing device adopts a spiral conveying system. The frozen products evenly distributed on the conveyor belt do spiral movement with the conveying chain. At the same time, the cold air passes through the material layer and the conveying chain to freeze the materials and recycle them. Mouth unloaded. It is suitable for freezing foods with small volume and large quantity, such as dumplings, siu mai, prawns, meatballs, fruit and vegetable fish fillets and cold snacks, and can also be used for freezing foods with large thickness, large volume and high feeding temperature, such as cut meat, Aquatic products, etc.
3. Tunnel Quick freezing
The shape is a rectangular tunnel, in which cold air circulates and food is frozen when passing through the tunnel. It can realize individual quick freezing (IQF) or plate block freezing (BQF) efficiently and economically.
Specific operation precautions in the use of quick freezer equipment:
1. Pre-cooling process. When the water tank is filled with the water required by a group of cold storage, the evaporator installed in the water tank absorbs heat and cools down, so that the water overflow drops to 6-101C, and then it can be added to the cold storage.
2. Before adding water to the cold storage, the spring movable bottom cover at the bottom of the cold storage must be sealed first. Therefore, before adding water, it is necessary to add a small amount of water to the cold storage, so that the wall of the cold storage and its bottom cover can be wetted. At the same time, turn the multi-way valve to the "cold storage" position, and inject ammonia into the interlayer of the barrel wall to evaporate and absorb. Heat, let the water on the barrel wall and the bottom cover freeze to seal the bottom of the barrel; then slowly add water to the cold storage.
3. During the injection process, the ammonia liquid will be sent to the interlayer of the cold storage through the multi-way valve in turn, enter the upper interlayer of the ammonia collector on the top of the finger-shaped evaporator through the top of the interlayer, and then enter the inner sleeve of the finger-shaped evaporator, and transfer to the The interlayer between the inner and outer pipes rises to the lower interlayer of the ammonia collector, and finally enters the ammonia liquid separator through the multi-way valve through the return air pipe. During this flow process, the ammonia liquid gradually evaporates and absorbs heat, causing the inner wall of the cold storage and the outer wall of the finger-shaped evaporator to freeze at the same time, and develop to the surroundings. It takes about 90-100 minutes to completely freeze into ice cubes.
The application of quick freezer is mainly for meat, poultry, aquatic products, pasta, fruits and vegetables and medicine.
