Freeze-drying equipment should move toward energy conservation and cost reduction
The products of the traditional packaging industry are mainly concentrated in the food box packaging, moon cake box packaging, hand bag, gift box, most of which have passed the food grade certification. Paper Bag,Handle,Hot Melt Glue Hetrun Industry Group Limited , https://www.hetrunindustry.com
At present, most domestic food lyophilizer manufacturers take the imitation road. Some manufacturers have made major improvements while adopting advanced foreign technologies. So how do freeze-dried devices improve?
Reduce costs and reduce energy consumption Some foreign freeze dryers do not use stainless steel, but use low-carbon steel to coat foods with a dryable resin that emits infrared light at room temperature. The surface of the shelf is coated with high-performance far-infrared emitting materials to enhance its radiation capability; the surface of the tray is treated to enhance its absorption capacity. The optimization of structure, size and frosting characteristics of the water trap is more practical because the current cost is equivalent to the cost of the freeze-dried box and the power consumption is large. For a lyophilizer, the heating system only supplements the heat of sublimation. The power consumption should not be too high, but the existing equipment is not satisfactory. The structure should be optimized and the energy consumption should be reduced.
Development of continuous freeze-drying equipment Most of the lyophilizers currently produced are batch-type products. With the development of a large number of industrial technologies, the development of continuous freeze-drying equipment and the increase of freeze-dried product output will be an inevitable trend.
Guarantee the application of the quality improvement performance in practice After some manufacturers' lyophilizers are installed, they cannot be put into normal production; some lyophilizers can produce but have high energy consumption. Some components continue to fail and affect normal production. Therefore, the quality of the freeze dryer must be guaranteed. Increasing performance means that new features of the equipment are enhanced in addition to heating rate, pumping rate, temperature uniformity, and vacuum stability.
With the increasing market demand for freeze-dried equipment and the continuous improvement of the quality requirements of pharmaceuticals, freeze-dried equipment will have considerable development. Freeze-dried equipment should be developed toward the industry's trend of energy conservation and cost reduction.
