When vacuum drying large quantities of powder or granulate, the vacuum cycles, which Memmert is the only manufacturer worldwide to offer, come into play perfectly: Two vacuum values can be set, between which the pressure is oscillated under controlled conditions. This way, a large amount of dry air is admitted within a short time, which absorbs humidity and is immediately extracted by the vacuum pump.
The spectrum for vacuum drying in a Memmert vacuum oven VO ranges from foodstuffs to cosmetics, granulate, watches, books, printed circuit boards, to electronic components or injection moulds.
Due to the low final vacuum of the speed-controlled, chemical-resistant vacuum pump of up to 2 mbar - the aforementioned is possible.
The demand-oriented pump control ensures a significantly longer service life for the membranes. The energy-saving potential is particularly impressive compared to an uncontrolled vacuum pump. With representative measurements in ramp operation, energy consumption was around 70 % lower, and even better values were achieved with a constant vacuum value.
The speed-controlled Memmert vacuum pump is automatically detected by every vacuum drying oven VO. In the event that another vacuum pump or a central vacuum supply is connected, the vacuum is controlled via solenoid valves.
Multi-Level-Heating & Sensing: intelligent direct heating via individually placeable thermoshelves with separate sensors guarantees short heating and process times in the Memmert vacuum drying oven. The control circuits react precisely to different loads or humidity and maintain a constant set temperature during vacuum drying. Thanks to the direct contact between the heating and the load, practically no heat loss occurs. Each thermoshelf can be individually calibrated.
