TH22007U - Infrared vacuum dryer - Google Patents

Abstract

Infrared vacuum dryers are ideal for producing dried products such as food, herbs, spices, and agricultural produce. They utilize two heating sources: 1) Hot air generated by a fan in a closed system, circulating hot air to the heating source; and 2) Infrared heat waves, which directly radiate heat to the product, causing rapid water evaporation. Both heating systems can be operated with an air extraction system to accelerate evaporation, making them suitable for heat-sensitive products or those requiring preservation of nutritional value. During drying, the trays can be rotated to ensure even heating. The dryer offers selectable hot air or infrared heating options.

Claims (2)

------22/09/2565------(OCR) 1. The infrared vacuum dryer consists of a drying chamber (1) with a geometric shape. The front of the drying chamber (1) is a drying door (2) with translucent openings at the top and bottom that allow visibility of the operation inside the drying chamber. Sealing material (10) is attached around the door (2) to prevent leakage and to help lock the door tightly, preventing air leakage during vacuum drying. The front of the drying door (2) is connected to several rotating arms (3) for opening and closing the door (2) and to help lock the door tightly. A unique feature is that on one side of the drying chamber (1) is a control cabinet (4) which controls the operation of the infrared vacuum dryer. A blower motor (5) is located on the lower side of the drying chamber, which draws hot air from inside the drying chamber and passes it through a heater box (14) to convert it into hot air. and is supplied as hot air to the side walls of the drying chamber which have hot air distribution vents (11) to create a hot air drying system. On one side, an infrared heat source (12) is installed, which directs heat waves onto the product drying trays (13) to heat the products in the trays. A vacuum system is installed outside the drying chamber (1) to create a vacuum. Air is conveyed through a vacuum pipe (6) and a vacuum pump (7) is used to help draw air during drying. The top of the drying chamber (1) is connected to a motor that rotates the shaft (8), which rotates the drying tray shaft (13). The top of the drying chamber (1) consists of an open-close air outlet pipe (15) to vent air, and the bottom of the drying chamber (1) is connected to a drain pipe (9) to drain water droplets resulting from the condensation of water vapor that evaporates from the dried products to the outside of the drying chamber (1). 2. Infrared vacuum dryer under claim 1, where the appropriate sealing material (10) is heat-resistant silicone. ------------ 1. The infrared vacuum dryer consists of a drying chamber and a control unit. Its characteristics are as follows: The infrared vacuum dryer consists of a drying chamber (1) which is of a geometric shape. The front of the drying chamber (1) is a drying door (2) with translucent openings at the top and bottom that allow visibility of the operation inside the drying chamber. Sealing material (10) is attached around the door (2) to prevent leakage and to help lock the door tightly, preventing air leakage during vacuum drying. The front of the drying door (2) is connected to several rotating arms (3) for opening and closing the door (2) and to help lock the door (2) tightly. On one side of the drying chamber (1) is a control unit (4) which controls the operation of the infrared vacuum dryer. A blower motor (5) which draws and distributes hot air is located on the lower side of the drying chamber. It draws hot air inside the drying chamber, passes it through a heater box (14) to convert it into hot air, and then distributes it as hot air to the side walls of the drying chamber. There is a hot air distribution channel (11) to create a hot air drying system. On one side, an infrared heat source (12) is installed to direct heat waves onto the product drying trays (13) to heat the products in the trays. There is a vacuum system installed outside the oven body (1) to create a vacuum. Air is conveyed through a vacuum pipe (6) and a vacuum pump (7) is used to help remove air during drying. The top of the oven (1) is connected to a spindle motor (8) which rotates the drying tray axis (13). The top of the oven (1) contains an air outlet (15) which is used to vent air, and the bottom of the oven (1) is connected to a drain pipe (9) to drain the water droplets that are formed from the condensation of water vapor that evaporates from the dried products to flow out of the oven (1). 2. An infrared vacuum dryer under claim 1, where the appropriate sealing material (10) is heat-resistant silicone.
