AI Technical Summary
During the food freezing process, liquid-immersed quick-freezers can easily lead to excessive temperature difference and food cracks, and the cost of liquid nitrogen freezing is high, which affects the effect of quick-freezing and increases production costs.
The cold air generated by the all-aluminum evaporator is circulated to the freezer box through a high-pressure fan. The food is blown from bottom to top in a fluidized state on the frozen transport belt, which increases the contact area between the food and the cold air, and uses the high-speed air flow generated by the high-pressure fan to achieve rapid freezing of the food in suspended state.
It improves the freezing efficiency, shortens the freezing time, retains the nutritional content and taste of the food, and reduces production costs.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of freezing equipment and relates to a fluidized bed quick-freezing machine for improving the quick-freezing efficiency. Background Art
[0002] With the improvement of the national living standard, people's requirements for diet are also getting higher and higher. The safety, flavor and nutrition of fresh food are inseparable from the freezing and refrigeration links, and the freezing process level directly determines the core value of food. Immersion quick-freezing is an efficient quick-freezing method. Its core lies in completely immersing food in food-grade quick-freezing liquid, and realizing rapid heat exchange through the direct contact between the liquid and the food. This efficient heat exchange method enables food to reach the expected frozen state more quickly.
[0003] When the immersion quick-freezing machine operates, due to the intense heat exchange when liquid nitrogen contacts food, a great instantaneous temperature difference will be generated, which easily leads to the formation of a temperature gradient between the surface and the center of the food, and easily causes the food to crack, affecting the quick-freezing effect; moreover, due to the relatively high price of liquid nitrogen freezing, 1.1 - 1.2 kg of liquid nitrogen is required to freeze every 1 kg of food, increasing the production cost. Content of the Utility Model
[0004] In view of the above problems existing in the prior art, the present application provides a fluidized bed quick-freezing machine for improving the quick-freezing efficiency.
[0005] The technical solution of the present utility model is as follows:
[0006] A fluidized bed quick-freezing machine for improving the quick-freezing efficiency includes a cold air box body. Inside the cold air box body, there are a full-aluminum evaporator I and a full-aluminum evaporator II. The cold air generated by the full-aluminum evaporator I and the full-aluminum evaporator II flows through a high-pressure blower to a freezing box body. Inside the freezing box body, there is a support frame passing through. The support frame is equipped with a freezing conveyor belt, and frozen food is placed on the freezing conveyor belt. The cold air box body is connected to a control cabinet. The left side of the freezing box body is connected to an input rack, and the input rack is equipped with an input conveyor belt. The right side of the freezing box body is connected to an output rack, and the output rack is equipped with an output conveyor belt.
[0007] As a preferred embodiment of the present utility model: The cold air box body is connected to a maintenance door through a hinge.
[0008] As a preferred embodiment of the present utility model: The maintenance door is installed with a handle.
[0009] As a preferred embodiment of the present utility model: The freezing conveyor belt is equipped with a driving roller and a tensioning roller.
[0010] As a preferred embodiment of the present utility model: The high-pressure blower includes high-pressure blower one, high-pressure blower two, high-pressure blower three, and high-pressure blower four, and a filter screen is installed on the high-pressure blower four.
[0011] As a preferred embodiment of the present utility model: A partition is provided between the cold air box body and the freezing box body.
[0012] The beneficial effects of the present utility model are:
[0013] The cold air generated by the all-aluminum evaporator flows through the high-pressure blower to the freezing box body. The food is distributed on the freezing conveyor belt inside the freezing box body. Under the action of the strong wind blowing from the bottom up, the food is in a fluidized state, thereby increasing the contact area between the food and the cold air, accelerating the freezing speed, enabling the food to quickly complete surface freezing and deep freezing in a suspended state. The high-speed air flow generated by the high-pressure blower quickly reduces the temperature on the surface and inside of the frozen food, thereby achieving the effect of rapid freezing, forming high-quality single frozen products, improving the freezing efficiency, achieving the ideal quick-freezing effect in a short time, greatly shortening the freezing time, well retaining the nutritional components and taste of the food, reducing losses, and lowering the production cost.
