The fresh food cooler machine is by the way of 3 level vacuum pumping via the water-ring pump; steam jetting system and an effective heat exchanger; and it can be fast, effective and energy saving to the vacuum system achieving, there is very low energy consuming can let the vacuum room fast to reach the vacuuming condition, and the energy of food product can be released in a short time, for achieving the energy saving and environmental protection effect.
The European IP69K sanitation grade of isolator can strengthen the sanitation grade, completely to prevent the secondary pollution when the food is cooling inside the vacuum box.
