Electric Grape Crusher Destemmer

The grape destemming and crushing machine is an important processing machine in the wine processing industry and the supporting equipment for the homemade wine-making workshop. This grape crushing machine mainly can remove the grape stems and crush the grape for the next winemaking process. This grape crusher can be matched with the hoist conveyor and the juicer machine in the grape wine processing line when using.

What is the fresh grape crusher de-stemmer machine

This equipment is a piece of special equipment for small wineries to process fresh grapes. It can be used for the separation of fruit stems, removal of stems and crushing, etc. It is ideal pre-treat processing equipment for small wineries. The machine has a high removal rate and can quickly remove grape stems. It has a very compact structure and is easy to install and move.

This grape stem removing and crushing machine is equipped with a hand-wheel for the step-less speed control device, which can adjust the speed of the machine according to the grape variety. In addition, the crushing roller gap of the machine can be adjusted, and the adaptability to grape varieties is stronger. The grape contacting part and the exposed part of the whole machine are made of stainless steel, which meets the standards of food-grade enterprises.

Components of the automatic grape crusher

This automatic grape crusher machine is composed of the stainless steel bracket and outer casing, one upper feed port and two lower discharge ports, screw shaft with cutter, speed control motor, etc. The crushing device of the machine is located at the lower end of the feed port and consists of two crushing rolls. The gap between the two rolls can be adjusted freely between 5-15mm, which can be determined according to the grape variety.

The grape de-stalking device of the machine consists of a stem removal shaft and a stem removal semi-screen. The stems are arranged in a spiral shape on the stem shaft. The semi-sifting sieve is formed by punching a stainless steel plate, and the main function is to separate the fruit and the stem, and the stem is discharged out of the grape crusher. The drive system of the de-stalking device is located at the front end of the frame and is driven by a step-less speed-regulating motor through a sprocket chain.

How does a grape destemmer work?

The grapes are transported directly from the feed hopper to the crushing system. The stem shaft in the crushing system will continue to rotate. In addition to the leaves on the stem shaft, the fruit pieces can be separated from the stems. The stem is spirally mounted on the main shaft, and the stem is discharged from the grape crusher by the end of the semi-screen.

The grape pieces after the stem are dropped from the round holes in the semi-sieve into the receiving tray and transported to the next process. The user can configure one screw pump according to his actual situation, and the fruit and slurry after the stem removal can be transported to the next process by the screw pump.

The whole bunch of grapes enter the conveying screw from the feed port and is conveyed to the sieve cylinder. When the sieve tube rotates, the mace device in the tube will break up the grapes and the stems. Then, the grapes are transported through the sieve holes(15-20mm) to the outlet and crushed by crushing rollers. The stem is discharged. The crushed grapes are transported to the next step by the screw pump.

How to install the grape crusher destemmer?

1. Before the automatic grape crusher installation, check the equipment for damage or missing parts during transportation.
2. The equipment installation site should be hardened to keep the machine horizontal and have good drainage performance.
3. The feeding mode of the equipment, the conveying method of the stems, the water supply, and the drainage method can be designed by the user.
4. If the ground is flat, the equipment does not need special fixing, it can be fixed by four M10 expansion bolts.
5. Each reducer and step-less speed governor should be injected with lubricating oil according to the instructions, apply grease on the drive chain, and inject a proper amount of lubricant into each bearing.
6. Users of the slurry pipeline should bring their own equipment. It should be convenient to install and minimize the curve. The conveying distance should not exceed 80 meters, and the conveying height should not exceed 10 meters. Shortening the transport distance increases the transport height.
