Description
For distillation equipment with larger volumes (approx. from 170 L) we recommend installing the vacuum intake of mash. It consists of several key components, as shown in the following diagram in the gallery.
The main element of the system is a water-circulating pump, available in several versions and supplied with a water buffer tank. The pump, when switched on, starts pumping air out of the pipe and creates a vacuum in the pre-pressure vessel via the safety (relief) vessel. This vacuum is then used to draw the mash from the storage tanks.
The pre-fill vessels are available in volumes from 170 to 500 L and can be equipped with a float mechanism that automatically switches off the vacuum pump when they are full. The tank can be preheated by the waste heat from the boiler, it can be equipped with a rinse and a DN 100 orifice. If the pre-fill vessel is not equipped with an automatic control system and the operator does not manage to switch off the suction in time, the pump is protected by a safety vessel which can be drained in case of mash entrapment.
Main advantages of vacuum suction:
- high comfort for the operator and customers
- clean working environment around the boiler
- increased effectiveness of the distillation process
