Fruit and vegetable processing
Juice pressing and bottling, drying, freeze-drying and jam making.
Basic information
About the plant
The juice press is housed in a separate single-storey building of the pavilion next to the Demonstration and Experimental Field. Its capacity is about 2,000 kg of fruit or vegetables. It mostly presses apples and pears, but the line can also handle other fruit and vegetables, above all carrots and beetroot.
On the 2nd floor, fruit and vegetables are dried and freeze-dried (also suitable for meat) and single and mixed fruit jams are made.
How we do it
The fruit is first washed and checked by the operators, who remove rotten fruit and debris such as leaves. The crushed fruit falls into a belt press with a capacity of up to 800 kg per hour. The raw juice is pumped into sedimentation tanks with conical bottoms; the next day the clear juice is pasteurised in a flow pasteuriser at 83 °C and filled into bag-in-boxes or glass bottles. Pasteurised juice protected from light keeps for more than a year.
Raw juice has a stronger taste and more vitamin C. It is sold on the day of pressing; store it below 5 °C and drink it within 5 days.
