Shanghai Haozhuang Instrument Co., Ltd. has developed the LNB brand freeze dryer, which is energy-saving and environmentally friendly, leading the country. Professional manufacturing is more secure and affordable Working principle ※ Moisture and high temperature compressed air flows into the pre-cooler (for high-temperature type) to dissipate heat, and then flows into the heat exchanger to exchange heat with the cold air discharged from the evaporator, which reduces the temperature of the compressed air entering the evaporator. The compressed air after heat exchange flows into the evaporator and exchanges heat with the refrigerant through the heat exchange function of the evaporator. The heat in the compressed air is taken away by the refrigerant, the compressed air is quickly cooled, and the moisture in the humid air reaches the saturation temperature and quickly condenses. The condensed moisture forms water droplets after condensing, and rotates at a high speed through a unique air-water separator. The moisture is separated from the air due to the centrifugal force, and the separated water is discharged from the automatic drain valve. The air pressure dew point after cooling down can be as low as 2 ℃. The cooled cold air flows through the air heat exchange and exchanges heat with the high temperature and humid hot air at the inlet. The cold air after heat exchange raises the temperature due to the absorption of the heat of the inlet air, and the compressed air also passes through the secondary condenser of the refrigeration system (Unique design) The heat exchange with the high-temperature refrigerant reheats the temperature of the outlet to ensure that the outlet air line does not condense. At the same time, the cold source of the outlet air is fully utilized to ensure the condensation effect of the machine refrigeration system and the quality of the machine outlet air. The main instrument of the machine and the main control switch description The main instrument of the machine is composed of the compressor air pressure gauge, refrigerant high pressure gauge, and refrigerant low pressure gauge; the main controller is composed of the ON / OFF button switch, the high and low protection switch of the refrigeration system, and the antifreeze switch. ①The air pressure gauge is installed on the instrument panel to display the pressure of the compressed air of the machine. The table is composed of several scales. Mpa and Kg / CM2 at the bottom of the table represent the unit value of pressure. When reading the pressure value, just observe the scale value corresponding to the pointer on the meter plus its relative unit value. ② The refrigerant low meter is installed on the instrument panel and is used to display the pressure or temperature of the low pressure end of the refrigeration system. The meter is composed of several scales and the reading method is the same as the high pressure meter. Remarks: The number of instruments and the configuration of different models are different for different machine models. The actual configuration is subject to the actual product.

A good mattress is essential for achieving quality sleep, impacting not only your comfort but also your overall health and well-being. Our extensive collection of bedroom mattresses offers a variety of types, materials, and firmness levels, ensuring you can find the ideal mattress that meets your unique sleeping preferences and needs. Whether you are a side sleeper, back sleeper, or stomach sleeper, we have options designed to provide optimal support and comfort throughout the night. Memory foam mattresses are among the most popular choices for their ability to contour to the body, providing excellent support and pressure relief. The viscoelastic foam responds to your body heat and weight, distributing your weight evenly and reducing pressure points, which can help alleviate aches and pains. Memory foam is particularly beneficial for those with joint issues or chronic pain, as it allows for comfortable alignment of the spine and joints. Innerspring mattresses, featuring traditional coil systems, are another widely favored option. These mattresses offer a classic feel and provide excellent support and breathability. The coils promote airflow, helping to regulate temperature during sleep. Innerspring mattresses come in various firmness levels, from plush to firm, catering to individual preferences. They often have a layer of cushioning on top to enhance comfort, making them suitable for various sleeping positions. Hybrid mattresses combine the best features of memory foam and innerspring mattresses, offering both support and comfort. These mattresses typically feature a pocketed coil system for support, topped with layers of memory foam or latex for added cushioning. This unique construction provides the benefits of contouring and pressure relief while maintaining a responsive feel. Hybrid mattresses are ideal for couples with different sleeping preferences, as they cater to diverse needs in one comfortable solution. Latex mattresses are known for their durability and natural materials, providing a bouncy yet supportive feel. Made from natural or synthetic latex, these mattresses are hypoallergenic and resistant to dust mites and mold, making them a great option for allergy sufferers. They also offer excellent breathability, keeping you cool throughout the night. For those who prefer a customizable sleeping experience, adjustable mattresses are available, allowing you to change the firmness level according to your preferences. Many of these mattresses come with dual firmness options, perfect for couples who have different firmness needs. Choosing the right size mattress is also essential for your comfort.
