Rice cooling device

Abstract

The invention belongs to the technical field of rice processing equipment, and particularly relates to a rice cooling device. The rice cooling device comprises a cooling chamber, wherein a plurality of rice conveying assemblies are arranged on the cooling chamber; a feeding hole is formed above the conveying head end of the rice conveying assembly at the topmost end; a discharging hole is formed below the conveying tail end of the rice conveying assembly at the bottommost end; a refrigerating device, a humidifying device, a temperature sensor and a humidity sensor are arranged in the cooling chamber; and the refrigerating device, the humidifying device, the temperature sensor and the humidity sensor are electrically connected with a controller assembly. According to the rice cooling device, the temperature and the humidity in the cooling chamber are detected through the temperature sensor and the humidity sensor correspondingly, the cooling chamber can keep constant temperature and humidity by means of the refrigerating device and the humidifying device, so that rice in the cooling chamber can be cooled to a proper temperature and keep proper humidity, the phenomenon that cracks appear on the surface of the rice is effectively avoided, and the problem that the rice is mildewed in a granary or a package due to overheating is solved.

Description

Technical field: [0001] The invention belongs to the technical field of rice processing equipment, in particular to a rice cooling device. Background technique: [0002] In the rice processing process, the dried grains are screened and then shelled in the wheel machine. When shelling, the rice will be affected by physical factors and heat up (up to 70 degrees), and when entering the rice polishing process, the rice will be affected by physical factors. Polishing its temperature will rise further. However, because the temperature rise is too high, rice is easy to dehydrate. If the rice needs to be stored in the granary, the pile of rice entering the granary should not be too high. A pile of rice that is too high will cause the heat to not be released, which will cause mildew of the rice. Shorten the shelf life of rice; if the rice needs to be packaged and transported, it will not be able to be packaged due to high temperature, reducing the shipment volume, and it will still ...

AI Technical Summary

Problems solved by technology

However, because the temperature rise is too high, rice is easy to dehydrate. If the rice needs to be stored in the granary, the pile of rice entering the granary should not be too high. A pile of rice that is too high will cause the heat to not be released, which will cause mildew of the rice. Shorten the shelf life of rice; if the rice needs to be packaged and transported, it will not be able to be packaged due to high temperature, reducing the shipment volume, and it will still be airtight and mildewed after packaging

[0003] Existing manufacturers generally adopt the following methods in order to cool down the rice: 1. Use a fan to cool the rice pile strongly, but the rice will lose too much water and cracks appear on the surface; To achieve the purpose of cooling, but it will cause the situation that the floor area is too large and the plant area is not enough
