Embodiment 1

[0020] This implementation mode takes fish and aquatic products as an example to illustrate the primary quick-freezing processing method, including the following steps:

[0021] The first step, selection, selects different types of fish and aquatic products, separates the same type of fish products, removes the internal organs and cleans them for processing, and selects fresh and clean aquatic products of the same type, preferably with no damage on the surface of the fish body Products, to be quick-frozen processing;

[0022] The second step, low temperature treatment, immerses the fish aquatic products to be quick-frozen processed in the first step in the temperature control mucus to cool the aquatic products to be quick-frozen processed to a constant low temperature, preferably 1 ton of 30% calcium gluconate as temperature control The mucus is added into the refrigeration tank, the refrigeration tank is surrounded by a refrigeration pipeline, the refrigeration pipeline is co...

Embodiment 2

[0026] This implementation mode takes shrimp aquatic products as an example to illustrate the primary quick-freezing processing method, including the following steps:

[0027] The first step, sorting, selects different types of shrimp aquatic products, separates the same type of shrimp products, removes the adhered debris and cleans them, selects fresh and clean shrimp aquatic products of the same type, and waits for quick-freezing processing;

[0028] The second step, low temperature treatment, immerses the shrimp aquatic products to be quick-frozen processed in the first step in the temperature-controlled mucus to cool the aquatic products to be quick-frozen processed to a constant low temperature, preferably 60% sodium gluconate 500gk as the temperature-controlled mucus Put it into the refrigeration tank, the refrigeration tank is provided with a refrigeration pipeline around it, the refrigeration pipeline is connected to the refrigeration compressor, and the concentration i...

Embodiment 3

[0032] This implementation mode takes crab aquatic products as an example to illustrate the primary quick-freezing processing method, including the following steps:

[0033] The first step, selection, selects different types of crab aquatic products, separates the same type of crab products, removes the adhered sand and stones and cleans them, selects fresh and clean crab aquatic products of the same type, and waits for quick-freezing processing;

[0034] The second step is low-temperature treatment, immersing the crab aquatic products to be quick-frozen processed in the first step in the temperature-controlled mucus to cool the aquatic products to be quick-frozen to a constant low temperature, preferably 40% sodium gluconate 120gk as the temperature-controlled mucus Put it into the refrigeration tank, the refrigeration tank is surrounded by a refrigeration pipeline, the refrigeration pipeline is connected to the refrigeration compressor, and the refrigeration compressor is tur...

Abstract

The invention relates to the technical field of aquatic product processing, in particular to an aquatic product primary quick-freezing processing method. The method comprises the following steps of 1,selection, wherein different types of aquatic products are selected and classified, and the fresh and clean aquatic products of the same type are selected out for quick-freezing processing; 2, low-temperature treatment, wherein the aquatic products to be quick-frozen in the step 1 are immersed into temperature control mucus to cool the aquatic products to be quick-frozen to a constant low temperature; 3, ice powder mixing and bonding, wherein a certain amount of ice powder is added into a mixer, and the aquatic products cooled to the low temperature in the step 2 are taken out and placed intothe mixer added with the certain amount of ice powder to be dynamically mixed, so that the ice powder is evenly bonded to the aquatic products; and step 4, quick-freezing in a refrigeration house, wherein the aquatic products bonded with the frozen powder in the step 3 are quickly put into the refrigeration house with a set temperature for quick-freezing. The process steps of the method are effectively linked and matched, so that the quick-freezing efficiency is promoted to be improved, and the energy consumption is reduced; and the method has wide application in the aquatic product quick-freezing processing industry.

Description

technical field [0001] The invention relates to the technical field of aquatic product processing, in particular to a product freezing processing method. Background technique [0002] After decades of development, my country's aquatic product processing industry has initially formed an industrial chain of aquatic products with a relatively complete processing system, including fishery refrigeration, frozen products, canned food, cooked food, dried products, pickled smoked products, fish meal, algae food, pharmaceuticals, etc. The processing system of chemical and health products and other product series has been formed. In my country's coastal areas, the aquatic product processing industry is at a relatively developed stage. However, the existing quick-freezing methods have low quick-freezing efficiency, long quick-freezing process time, high energy consumption, large amount of materials, and complicated quick-freezing methods. Seriously restrict the further improvement of m...
