Fruit and Vegetable Crushing Machine Introduction

The fruit crushing machine is an important processing station of fruit pre-processing equipment. Fruits and vegetables are crushed before juicing or beating, which can improve the juice yield. Especially, fruits with dense skin and flesh need to be crushed, but the crushing particle size needs to be appropriate, which is more conducive to the pressing process. Different juicing methods require different pulp particle size, generally controlled between 3-5mm, the crushed particle size is uniform, does not contain particles larger than 10mm, and the particle size of fruit mash can be controlled by the aperture of the sieve plate. When crushing, an appropriate amount of antioxidants such as vitamin C can be added to protect the color and nutrients of the juice.

Fruit mechanical crushing is a unit operation that uses mechanical force to overcome the internal cohesion of solids to achieve crushing and grind. The forces that fruit raw materials are subjected to when they are broken or crushed include extrusion force, impact force and shear force.

At present, the production of fruit juice or pulp is mostly mechanical crushing. But for the production of different juices, the crushing process is also different. Such as the production of clarified juice, generally can use hammer crusher, tooth crusher, centrifugal crusher, after the raw fruit is moderately crushed, the pulp is pretreated to inactivate enzymes, and then it can be sent to the next juicing process; if the turbid juice with flesh is produced, a crushing and beating machine and a tooth-type fruit colloid mill can be used.

 This article will mainly introduce the most commonly used fruit crushers in the fruit and vegetable processing field.

This hammer crushing machine is the most used fruit crushing machine in fruit and vegetable processing plant. It can be used to crush all the fruits and vegetables basically. It consists of a side cover, flying blade, sieve, machine body and spindle etc.

The whole machine is composed of material feeding hopper, side cover, machine body, spindle, bearing seat, motor, machine frame and material discharging hopper.

During operation, the motor will drive the spindle at a constant speed to rotate through a pair of pulleys. The spindle is installed with flying blade for high-speed rotation. The materials drop into the feeding hopper through the lifter and are crushed by flying blade rotating at high speed. Due to the function of centrifuge force, the material will drop into the storage tank from the sieve with waist-shaped holes, and then will be transferred to the next procedure by the pump.

The advantage of the hammer crusher is the fruit crushing size is even, the size of the crushed fruits depends on sieve with waist-shaped holes.

Technica parameter of fruit hammer crusher 

The squirrel cage crusher is suitable for crushing all kinds of fruits and vegetables, such as apples, pears, tomatoes, wheat seedlings, etc. (except stone fruits).

Working principle: The materials are lifted into the hopper and enter into the crushing area by the spiral material feeding cover. Under the function of centrifuge force, the materials will rotate with the scraper on the rotor, during rotation on the rotor, the blades installed on the stator are crushing the materials, after crushing to a certain size, the materials will be discharged from the waist-shaped or round holes on the stator, then transferred to the next station by pump or spiral propeller. The machine side covers provide safety production during production, the blades on the stator are double-face structures and can be adjusted for use.

Technical parameters of squirrel cage crusher

The machine is mainly used to crush all kinds of fruit and vegetables. It is composed of a machine body, blades, spiral and spindle material pushing device. After materials enter into the hopper, the material pushing spiral will extrude the materials to the blade disc crushing area, the crushing materials will be thrown into the low position vat through blades by the centrifugal force.
