Fruit screening and preservation coating machine

Abstract

The invention discloses a fruit screening and preservation coating machine. The equipment comprises a screening device and a coating device, the screening device comprises at least two discharging ports for conveying each grade of to-be-coated fruits, and the coating device comprises a dip-coating tank containing a coating liquid, a fruit conveying pipeline arranged in the dip-coating tank and corresponding to the discharging ports, a fruit output pipe connected with the fruit conveying pipeline and inclining upwards relative to the fruit conveying pipeline and an air-drying unit, a liquid inlet is formed in the pipeline wall, a first fruit conveying mechanism is arranged on the bottom side, a second fruit conveying mechanism is arranged on the wall of the fruit output pipeline, and the air-drying unit comprises an air-drying pipeline connected with the fruit output pipeline. The machine puts fruits of the same sizes into the fruit conveying pipeline after screening the fruits, the inner diameters of the air-drying pipeline, the fruit output pipeline and the fruit conveying pipeline are set to be adapted to outer diameters of to-be-coated fruits, fruits are coated gradually and air-dried along the pipelines, and the coating efficiency and the air-drying efficiency are high.

Description

technical field [0001] The invention belongs to the technical field of fruit fresh-keeping, and in particular relates to a fruit screening and fresh-keeping coating machine. Background technique [0002] Fruits can provide vitamins, minerals and organic acids that are easily lacking in the human body to ensure people's health, so they have become an important food that people like. However, after fresh fruits are harvested, complex physiological changes, biological changes and physical changes are still taking place, and cells and tissues are still undergoing respiration and transpiration, which makes the fruits prone to shrinkage, weightlessness, wilting, deterioration and other phenomena, affecting fruits and vegetables. quality and sales. [0003] In the process of fruit transportation and storage, in order to achieve the effect of preservation and preservation, physical preservation methods are often used, such as controlled atmosphere refrigeration. Because the storag...

Problems solved by technology

[0006] The fruit and vegetable vacuum coating machine uses a box-shaped dipping rack to load fruits and vegetables. Since the coating is carried out in units of the dipping rack, in order to improve the coating efficiency, more fruits and vegetables are usually loaded in the dipping rack, and the fruits and vegetables are stacked on top of each other. The setting is not conducive to the subsequent air-drying of the film, resulting in long air-drying time and low air-drying efficiency; moreover, the staff need to continuously load fruits and vegetables into the dipping rack, which has high work intensity and low degree of automation
