Abstract

------ 19/09/2018 ------ (OCR) page 1 of number 1 page invention summary This invention focuses on the creation of heat pump dryers for agricultural and processed agricultural products, herbs and pharmaceuticals, consisting of two main components: 1) drying chamber and 2) The heat-knot set in which both parts have an external structure that is independent of each other. This thermal knot dryer can be operated in two modes: 1) Drying mode which operates in an open system using the ambient air as the drying air. And ventilate the humid drying chamber outside the drying chamber, and 2) the thermal knot drying mode, which operates in a closed system whereby the drying air is circulated inside the drying chamber. The drying chamber is divided into 3 parts according to the different functions: 1) drying area, 2) mixing area, hot and dry air exiting the heat knot and air leaving the drying area. And 3) the area used as a channel for the drying air between the drying area of the inlet drying air and the drying area of the return drying air. Circulation of the air inside the drying chamber in the operating mode by the heating knot and the delivery of ambient air into the drying chamber. In the drying mode, humid drying is achieved through the operation of a recirculating fan installed in the Z-shaped interior wall inside the drying chamber. There are openings on the walls and ceilings with adjustable air shutters. Which is used to emphasize the channel of external ambient air flow to the inside of the drying chamber And is used to focus on the dried damp air vents that have been dried out to the outside of the drying chamber Trolley for production of bowels can be pushed into and out of the drying room. The heating element consists of four main components: 1) compressor 2) evaporator. 3) Condenser and 4) Expansion valve, also a fan blowing air through evaporator. And the exhaust fan through the condenser They are all housed inside a heat pump jacket, which has a rectangular exterior accent and can be separated from the drying chamber structure. The heat pump assembly is mounted on one side of the drying chamber. Additionally, the heat pump unit is designed to partially dry the drying air through the evaporator and condenser. By limiting the cross-sectional area, the air flow passed through the evaporator. And the condenser to be less than the cross-sectional area of the drying air flow within the drying area ------------ page 1 of the number 2 pages. This invention is the creation of a heat pump dryer for agricultural and agricultural processing, herbs and medicine, which consists of two main components: 1) a drying chamber and 2) a heating knot, with both parts structured. Outside that are independent of each other Pump drying machine This heat is characterized by its high efficiency. Energy saving Short drying time, easy to expand drying chamber to increase productivity. Convenient for maintenance and maintenance And another important thing It can work in two modes: 1) drying mode, which works in the form of an open system using air. The outside environment is drying air. And ventilate the humid drying chamber outside the drying chamber, and 2) the thermal knot drying mode, which operates in a closed system with the drying air being Circulating in the drying chamber, in which only one operating mode can be selected Alternatively, two modes can be run continuously in a sequence for high energy efficiency. The drying chamber has a rectangular shape, arranged horizontally. Which makes it easy to expand capacity By extending the drying chamber horizontally and making it easier to distribute the drying air evenly Throughout the transverse of the drying chamber Inside the drying chamber is divided into 3 parts according to their duty. The differences were 1) the drying area 2) the hot and dry air mixture area from the pump unit. Heat and air exiting from the drying area and 3) the drying air channel area. Between the drying area of the go-leg drying air and the return-leg drying air drying area Circulation of the air inside the drying chamber in the operating mode by the heat pump unit and the air delivery. The environment enters the drying room And ventilation, drying the damp to the outside in the mode of Drying is achieved through the operation of a recirculating fan that is attached to the Z-shaped interior wall inside the drying chamber. There are openings on the walls and ceilings with adjustable air shutters. Which is used as a flow channel Of the external ambient air entering the drying chamber And used as a vent for drying through the damp Drying and then exiting outside the drying chamber The trolley for the production of the knot can be carried in and out of the drying chamber. The heating knot consists of four main components: 1) compressor, 2) evaporator, 3) condenser, and 4) expansion valve. The thermo-dynamic principle of the cooling cycle in general. In addition, the fan blows air through the evaporator. And the exhaust fan through the condenser They were all trapped inside the amorphous heat-knot clothes. The external structure is a rectangular box. And can be separated independently from the structure of the drying chamber The heating knot is mounted on one side of the drying chamber. Moisture or steam is reached. It comes out of the dried air by condensation of water vapor into the air and becomes water droplets. Dry the air from the evaporator. Therefore, after increasing the temperature at the condenser on page 2 of the next 2 pages. Therefore hot and dry drying air has the ability to easily absorb moisture from the product, shortening the drying time. And to save energy in drying, the air flowing from the condenser is not high temperature. Therefore can maintain the quality of the product after It can be dried in terms of color, smell, appearance, texture (texture), as well as nutritional value and the value of active ingredient in herbs and drugs. Designed to be used in conjunction with the aforementioned drying chambers, it also has another notable feature: a low power rating (kW) per unit mass (kg) of product. Which is the result of surrendering Partially allow air to dry. (Not all) flows through the evaporator and condenser by limiting the cross-sectional area of the air flow passing through the evaporator. And the condenser to be less than the cross-sectional area Drying air flow within the drying area Thus making the moisture in the air dry gradually Decrease and the temperature of the drying air gradually Each cycle of the air circulation in the drying chamber increases, resulting in the evaporator cooling load and the heating load of the drying chamber. The condenser is not too high. Reduce power consumption And the size or coordinates of the heat knot Not necessarily high
