Problems solved by technology

However, the air flow direction of the existing heat exchange system is usually an annular air flow, and the air flow passes through the conveyor belt horizontally. The air circulation utilization rate of this method is low, and it cannot meet the needs of the existing large-scale food quick-freezing, and most of the existing technology is a section Conveyor belt, unable to adjust the speed more accurately according to the cooling condition

Embodiment 1

[0041] see Figure 1-3 , a fluidized quick-freezing machine, including a frame 1, a thermal insulation storage body 10, a cleaning and drying device, a material delivery system, a refrigeration system, a frosting system and an electrical control system.

[0042] The frame 1 main body is arranged in the heat preservation storehouse body 10, and its left and right ends respectively protrude from the heat preservation storehouse body 10 inlet and outlet, and the left and right ends of the frame 1 are all provided with temperature sensors (not shown in the accompanying drawings due to the angle of view). ).

[0043] The thermal insulation storage body 10 includes inner and outer stainless steel plate layers and a polyurethane thermal insulation layer in the middle, wherein the thickness of the stainless steel plate layer is 2.3mm, and the thickness of the polyurethane thermal insulation layer is 20cm.

[0044] The material conveying device includes 9 drive rollers installed on th...

Embodiment 2

[0056] A kind of fluidized quick-freezing method, this method is applied to a kind of fluidized quick-freezing machine in embodiment 1, and this method comprises:

[0057] When the fluidized quick-freezing machine is first started after installation, in order to prevent damage to the conveyor belt due to improper installation or adjustment, it is necessary to conduct a low-speed test run after a comprehensive inspection of the device.

[0058] Before starting, it is necessary to check whether there are foreign objects on the conveyor belt, especially the lower conveyor belt. When the temperature inside the heat preservation storehouse 10 is below -15°C, the transmission system must not be started immediately. Before starting, the ice and other sundries on the components of the transmission system must be checked and removed to prevent foreign matter from entering the transmission mechanisms and causing damage.

[0059] Before starting, you should also confirm whether the elect...

Abstract

The invention discloses a fluidized instant freezer and a fluidized instant freezing method. The fluidized instant freezer comprises a frame, a thermal insulation storage chamber, a cleaning and blow-dry device, a material conveying system, a refrigerating system, a defrosting system and an electrical control system. The method includes steps of examination, starting and stopping. By combination of a fluidized instant freezer and a tunnel instant freezer, different freezing requirements of different products including vegetables, aquatic products, meats and the like can be met, and the fluidized instant freezer is real ideal novel multipurpose instant freezing equipment. An evaporator is changed from a horizontal mode into a vertical mode, and high freezing efficiency, short time, reasonability in air distribution and low energy consumption are realized; by combination of mechanical pulse and high-pressure airflow, high freezing quality and freeness of caking are realized; a one-stagespeed control mode of a material conveying belt is changed into two-stage respective speed regulation, so that great material freezing effects can be guaranteed, and material caking can be prevented.

Description

technical field [0001] The invention belongs to the field of food freezing equipment, in particular to a fluidized quick-freezing machine and a fluidized quick-freezing method. Background technique [0002] Quick freezer is a high-efficiency freezing equipment that can freeze a large amount of products in a short time. It can effectively and economically freeze a variety of products placed inside the quick-freezing machine, such as various shapes of meat, fish, shrimp, meatballs, vegetables, prepared foods, dairy products, etc. The quick-freezing machine is mainly composed of a refrigeration system, a propulsion system, It is composed of electrical control system and quick-freezing chamber. The staff will put the frozen product tray with the food to be frozen into the quick-freezing track through the quick-freezing entrance and move it step by step towards the exit direction under the action of manpower. The vertical ring-shaped low-temperature airflow, which exchanges hea...
