Dried nut storage bin and working method thereof

Abstract

The invention relates to a dried nut storage bin and a working method thereof. The invention provides the dried nut storage bin, which has a simple and ingenuous structure, can implement cooling softening, sterilization, online weighing and automation production of materials and effectively avoids deterioration of jujubes and egg breeding in a processing process of the jujubes, and the working method thereof. The dried nut storage bin comprises a bin body, a feeding system, a discharging system, a ventilating system and a sterilizing system, wherein strip angle-shaped boxes are fixedly and uniformly distributed in the bin body; the ventilating system comprises a plurality of layers of branch pipe groups, a main pipe and a fan; each branch pipe group comprises a plurality of branch pipes; and the sterilizing system comprises an ozone generating device communicated with the main pipe. According to the invention, aiming at two common deterioration factors of the jujubes, the ventilating system is additionally arranged in the storage bin, so that various bacteria are effectively prevented from breeding in the jujubes. According to the invention, eggs and residual bacteria in the jujubes are subjected to collective killing and elimination in an ozone sterilizing mode, so that the jujubes can accord with the national hygiene and food safety standard after being discharged from the storage bin.

Description

technical field [0001] The invention relates to the field of deep processing of agricultural by-products, in particular to the improvement of a dry fruit storage bin. Background technique [0002] Jujube (such as jujube, jujube) is a common dried fruit, and its most prominent feature is its high vitamin content. A clinical study in foreign countries showed that patients who ate red dates continuously recovered more than 3 times faster than those who simply ate vitamin medicine. Therefore, jujube has the reputation of "natural vitamin pill". The traditional processing technology usually consists of raw material selection, grading, blanching, drying, softening, grading packaging and finished products. Among them, the softening process generally uses baskets and plastic wrap to stack the dried red dates for 7-15 days. sky. [0003] However, due to the temperature (50°C-65°C) of the dried red dates, it is easy to ferment and deteriorate the red dates when they are directly pi...

AI Technical Summary

Problems solved by technology

However, after applying it to the jujube production line, the operators found that the dried jujube itself carries a small amount of oxygen and water inside. On the one hand, the vacuum pump cannot achieve a complete vacuum, and the vacuum has high requirements on the sealing and material of the warehouse. , the processing cost is high; the vacuum condition cannot kill the pathogenic bacteria, once the material is out of the warehouse, the pathogenic bacteria carried on the material still survive; It is also more prone to fermentation and deterioration in space
