The Introduction of Fruit and Vegetable Washing Machine

The cleaning of fruits is mainly through the mechanical force of physical methods (soaking, air blowing, agitation, spraying, brushing washing, vibration washing, etc.), or chemical methods (cleaning solution) to clean the dirt on the surface of raw materials.

Soaking type: Soak in a flume or a stainless steel water tank. The fruit is soaked for a period of time, so that the pollutants adhered to the surface are loosened and floated in the water, and then discharged by changing the water. In order to enhance the cleaning efficiency, chlorine dioxide, ozone and other cleaning agents can be added to the water, soaked at room temperature for several minutes, and then washed with clean water.

Air bubbling type: Blast cleaning is to install of pipes in the cleaning tank, and a certain number of small holes are opened in the pipes, and then high-pressure air is used to form high-pressure bubbles. Under the vigorous stirring of high-pressure air, the fruits are continuously rolled in the water, so that the dirt comes off the fruits.

Spraying type: Spraying is generally carried out after soaking. The typical spraying method is to install a high-pressure water nozzle on the elevator. When the material on the elevator passes through, the nozzle sprays on the material. The efficiency of spray cleaning is related to the water pressure, the distance between the nozzle and the material, and the water consumption. Generally, the effect of small water volume and high pressure is better.

Friction stirring type: Friction stirring is to use the paddle agitator to contact and rub with the material during the soaking and spraying process, and at the same time, the materials are in contact with each other, so as to achieve the purpose of cleaning.

Brushing type: Use a brush to clean the sediment and dirt on the surface of fruits, which is suitable for cleaning various fruits and root materials.

In the field of deep processing of fruits and vegetables, it is very important for the entire production line to configure a good fruit washing machine. A high-performance fruit and vegetable washing machine can quickly and efficiently remove foreign objects and pesticide residues on the surface on the surface of fruits and vegetables, but also reduce microorganisms and kill bacteria, which can ensure the cleanliness and hygiene conditions of fruits and vegetables and provide sufficient conditions for the production of high-quality fruit puree, paste, jam or juice.

We will give one brief introduction of several main washing machines in fruit and vegetable processing.

This type of brush washing machine is suitable for washing round and oval fruits and vegetables. Like mango, orange, carrots, onion, pineapple, ginger, beetroots. The equipment is composed of tank body, geared motor, transmission device, brush, spray pipe, universal brake wheel and other main parts. The whole machine is made of SUS304 stainless steel, and the brush is made of wear-resistant food-grade nylon. Choose different hard grade brushes, the machine can be used for washing or peeling fruits. It has the characteristics of large cleaning effective volume, high efficiency, water saving, continuous cleaning, simple operation and long service life.

The drum washing machine is made of SUS304 material, it is suitable for washing almonds, jujube, ginger, cheery, peanut, beans, and walnuts. The equipment is composed of reducer, water pump, drum, supporting wheel, spray pipe, hopper, water tank, valve, driveshaft, electrical control and other parts. The long shaft sprocket is driven by the motor sprocket through the chain, and the sprocket of the transition shaft engages with the stainless steel chain on the drum to drive the drum to rotate. After the material enters the drum, it is flushed by the water spray pipe and the drum is turned and rolled material to achieve the cleaning effect. The rotation speed of the drum and the amount of spray water can be adjusted.

The air bubbling washing machine working principle is that there is certain amount of water in the water tank. When the raw fruit passes through the water tank, it will be rolled over under the combined action of the bubble machine and water, and continue to advance with the mesh belt. When the fruits are transmitted to the water surface, the upper part is equipped with a water sprayer to do high-pressure washing. The high-pressure water stream makes the material tumble, removing pesticide residues on the product surface, and floating objects in the washing machine can overflow and the sediment is discharged from the waste outlet to achieve the purpose of cleaning. At the same time, the machine is equipped with a clapboard, which effectively separates the cleaning material from the washed sediment, reduces the turbidity of the water, greatly improves the recycling rate of the cleaning water, and can save 80% of the cleaning water and save manpower; Convenient operation, saving time and effort, low energy consumption, sanitation and high efficiency. It is suitable for washing and cleaning most fruits and vegetables like tomatoes, mango, pineapple, passion fruit, banana, coconut meat.
