Adopt the pipeline heat-exchanger rig of forced circulation, the characteristics of distributed parameters that can adapt to oddment better carries out heat exchange, and has the high-power advantage of heat exchange, but circulating pump needs to consume a small amount of energy.
Adopt source pump by heat or the heat exchange interface of pipeline heat-exchanger rig absorb heat from freezer have power large, be applicable to high humility grain needs and dewater as early as possible and prevent the too high demand burning out grain of temperature, source pump just can not be relied on to lower the temperature after short time dehydration later; Certainly, negative pressure source also can be adopted in this case to comprise Roots blower and to realize dehydration cooling to provide low vacuum or negative pressure.
Adopt source pump or solar energy to heat cool house internal, the requirement that some fruit can not be too low to storage temperature can be realized.Source pump heating power is large and energy-conservation.Utilize solar energy heating then can not electricity consumption.
Temperature due to oddment remains very low, and the free fatty of rice can be gone through and still keep extremely low level for many years.Both can reduce paddy to have to, as the sight of feed process waste grain, consumer can be made again to enjoy the cereal of better quality with regard to ageing one or two years.
Adopt digital control hoist engine can control the decline state of tubular warehouse and give steel core rack uniform pulling force, realize prestressing force effect.Adopt to refute and connect rigid body or ring-type and refute and connect the stressed safety that rigid body can guarantee tubular warehouse, by or the impact of few tower crane accident by occurring.Equally, the state in its manufacture process controls and good operating mode to adopt digital control hoist engine to guarantee to stainless steel thin-wall lining container.
