Press trolley: design and purpose

Press trolleys are used in the production of tvorog (quark) or soft cheeses, and can also be used to remove liquid from other products. When preparing curd mass for glazed curd snack bars, they replace bulky bag presses.

Press trolley design

A press trolley is a welded structure in the form of a rectangular vat fitted with a perforated insert, which serves as the working surface, and a screw press that applies mechanical pressure. The trolley can be moved around the workshop on swivel castors and is braked with a built-in stopper. For convenience it has a folding handle and can be moved to any production room.

The pressing process

Press trolleys are mainly used in the separate method of tvorog production. After the curd coagulum has been fermented in the vat, the resulting mass is filled into canvas or lavsan (polyester) bags and placed in the trolley. Depending on the required moisture of the final product, pressing is done either by self-pressing (if high moisture is required) or by the mechanical action of the press (the pressure is adjusted manually with the screw). The perforated surface lets the whey drain freely. To distribute moisture evenly in the product, the bags should be swapped around periodically. When pressing is complete, the mass should be left to rest for 1–4 hours at 8 °C. Soft cheeses and other products are pressed on the same principle.

Tips for choosing a press trolley

A press trolley is useful both for small tvorog (cheese) producers and for medium-sized plants with a closed production cycle.

It is important that the trolley is made entirely of stainless steel approved for the food industry. This material is easy to clean and disinfect, ensures hygiene and product safety, and releases no harmful substances.

It makes more sense to buy a trolley with the maximum yield of final product, as this lowers the cost per unit of product.

The Milberg plant offers a wide range of equipment for producing tvorog and cheese, suitable for both small family farms and large plants. In line with food safety and hygiene standards, all equipment manufactured at our plant is made of high-quality stainless steel approved for use in the food industry.
