Cooling device of baked salt

Abstract

The present invention provides a cooling device of baked salt. A spiral push rod is set up in a cooling cylinder; a spiral blade is arranged around the spiral push rod; the outer edge of the spiral blade is in a clearance fit with the inner wall of the cooling cylinder; the axial direction of the cooling cylinder is arranged along the lateral direction thereof; during the rotation of the spiral push rod, the baked salt is pushed to convey along the axial direction of the cooling cylinder; during the pushing process, the spiral blade stirs the baked salt in the cooling cylinder; the outer wallof the cooling cylinder is provided with a cooling device; during the stirring of the baked salt by the spiral blade, the baked salt in the cooling cylinder is stirred from inside to outside; the baked salt is cooled during the bonding process of the baked salt and the inner wall of the cooling cylinder; due to the fact that the baked salt is synchronously stirred during the cooling process, agglomeration of the baked salt during the cooling process is avoided; at the same time, the spiral blade conducts stirring of the baked salt; the inner wall of the cooling cylinder conducts cooling of thebaked salt; the temperature inside and outside of the baked salt is cooled evenly to avoid uneven heating problem; and at the same time, the cooling device is used to improve the cooling efficiency of the baked salt.

Description

technical field [0001] The invention relates to the technical field of table salt, and more specifically, relates to a baking salt cooling device. Background technique [0002] Roasted salt is generally made of high-quality natural sea salt as raw material, which is washed to remove impurities, baked at high temperature, crushed, iodized (or not), and packaged. Baked at a high temperature of 800 degrees Celsius, the bad microorganisms in the raw salt are effectively removed, making the salt more pure and hygienic. [0003] After the roasted salt is finished, the roasted salt needs to be cooled for easy packing. The cooling of roasted salt in the prior art is to put the roasted salt into a bucket and cool it by natural cooling. Due to the way of natural cooling, the baked salt is laid in the bucket in a layered manner, which will cause the problem that the surface of the roasted salt is cooled and a certain temperature remains inside, and the cooling efficiency is low, whic...

AI Technical Summary

Problems solved by technology

Due to the way of natural cooling, the baked salt is laid in the hopper in a layered manner, which will cause the surface of the roasted salt to cool and still have a certain temperature inside, and the cooling efficiency is low, which is prone to the problem of roasted salt cooling
