Grape crusher with crest separator VGD-20: crushes grapes with previously separated ridges. It is used for the line of primary processing of grapes with productivity - 20 tons per hour.
The VGD-20 crusher is an aggregate consisting of two units with separate drives: comb-separator and a crusher.
The unit operates depending on the type of grape being processed, the type of wine. The crest-separator carries out the following technological operations:
For grinding grapes, without separating crests, roll crusher, without a comb separator mounted over a drain hopper or press. The design of the comb combiner consists of a stainless perforated cylinder and a shaft. While working a combed separator, under the blows of the shaft, the crests are separated from the grape berries, removing from the perforated cylinder, the berries flow through the perforation of the drum on the rotating rollers of the crusher.
Equipped with devices for adjusting the inter-roll gap, in the range of 3-8 mm, which allows the process of grinding grapes in a sparing mode, depending on the grape variety, its physical characteristics, to receive a wort of high quality, with a minimum mass fraction of suspensions.
When using VHD-20, loss of wort is reduced with crests, the enrichment of wort with the substances that give it a taste of grass is excluded.Rotation speed of the crushers roller, rpm - 156.
