Which is a good freeze-drying machine

Laboratory freeze dryer Pilot2-4LDFeatures:

1.The transparent door of the drying chamber is made of aviation acrylic material, which has high strength and no leakage.

2.Pre freezing function of the board layer.

3.Nitrogen or inert gas can be filled for storage after drying.

4.Freeze drying automatic control system: programmable control from freeze-drying to defrosting.

5.Board layer heating control system: independent temperature control for each layer, thermal cycle monitoring and protection, special heating materials, fuzzy PID control algorithm.

6.Cold trap defrosting system: non electric heating defrosting method, high safety performance; Fast defrosting speed, solving the problem of traditional soaking defrostingThe inconvenience caused by frost.

7.Korean brand vacuum pump with high pumping speed, low noise, and standard oil mist filter.

8.Automatic drawing of freeze-drying curve function, program pre freezing function, vacuum protection during product freeze-drying process, vacuum pump startup protection.

9.Adopting an industrial touch screen, it has good human-computer interaction, is simple and easy to understand, and can be operated easily without the need for instructions.

Laboratory freeze dryer Pilot2-4LDKey points of process：

The influence of high or low solution concentration on the surface quality of traditional Chinese medicine liquid during the drying process. When the solution concentration is too high: it is dried to form a dense surface layer. The surface pores are small and have poor breathability, making it difficult for the moisture inside to pass through the surface layer, thus rising along the bottle wall and causing the product to detach from the wall; In addition, when the concentration is too high, the medicinal solution is prone to clumping during the freeze-drying process, resulting in uneven appearance of the resulting product. When the concentration is too low: the mechanical strength is low, and the structure of the product is relatively loose or even turns into powder after packaging and transportation, which affects the appearance of the product.
