Cold-pressed juice
Making cold-pressed juice is a two-step process. The first stage is to shred the fruits and vegetables into a pulp. Typically the shredding process uses a steel rotating disc. Produce is loaded into a large hopper feeding tube and typically falls into a filter bag. The second process is the hydraulic press; this exposes the shredded produce to extreme pressures between two plates. The pressure causes the juice and water content from the produce to drip into a collection tray below, leaving behind the fibre content in the filter bag. The fibre left behind is generally composted, recycled in food products or discarded.
Climbing and falling film plate evaporator
Fruit juices are condensed by evaporation for storage, transport and commercial use. If fruit juices are exposed to heat, the nutrient content such as vitamin C may be affected. Furthermore, these nutrients are easily oxidized at high temperature. The evaporator can overcome this constraint as it operates at high feed flow rate and small temperature difference. In addition, the change in color and texture of the juices can be prevented via the operation of this evaporator type.
