Product Features

Shandong Leader Machinery Co.,ltd. is use of reverse Carnot principle .With free air to absorb heat and transfer it to the drying chamber, Heat Pump Dryer drying room temperature to achieve improved, with the appropriate humidity and dehumidification equipment to achieve dry materials. heat pump dryer Compressor - heat exchangers - Chokes - heat sink (outside the machine) - Compressor and laundry dryer other devices constitute a refrigerant cycle system. Shandong Leader Machinery Co.,ltd. Under the action of the compressor in the refrigerant circulating in the system flow, it is done in the gaseous booster compressor heating process (temperature up to 100 ℃), releasing it into the machine dry in room temperature air heated by the heat, while they have been and converted to liquid cooling flow, when it runs out machines,Shandong Leader Machinery Co.,ltd. liquid absorbs heat quickly evaporates once again transformed into a gaseous state, while the temperature dropped to minus 20 ℃ --30 ℃, then the air around the heat sink will continuously transferring heat to the refrigerant. Heat Pump Dryer Refrigerant continuous cycle to achieve the heat in the air transport to the drying room heating room air temperature to achieve the purpose of dry material.

6.Conventionally, materials are dried either in the field (sun drying) or using high temperature dryers (electric, gas fired, etc.). Successful outdoor drying depends upon good weather and indeterminate weather can render a product worthless. High temperature drying can damage the nutrient content and impart an unpleasant smell to the dried product.

Specialty crops such as ginseng, herbs, echinacea, etc., need to be dried at low temperatures (30 - 45C) for product quality optimization. This is an important consideration as they have a relatively high commercial value. Heating ambient air to use for drying, although a simple cost-effective procedure, is of limited application, particularly at higher ambient air relative humidities because of the low allowable maximum temperature conditions. Under high ambient moist air conditions, it may not even be possible to dry the material by conventional means. High temperature drying deteriorates the material structure and can render it unsuitable for further use. Low temperature drying of specialty crops reduces the risk of loss in nutrient content and damage to physical properties. Drying system incorporating a dehumidification cycle have been developed that both conserve energy and handle the material gently. The dryer operates using a heat pump where both sensible and latent heats are recovered from the exhaust air. The heat is then recycled back through the dryer by heating the air entering the dryer. The heat pump drying system is a combination of two sub-systems: a heat pump and a dryer.

The heat pump operates according to a basic air conditioning cycle involving four main components: the evaporator, the compressor, the condenser and the expansion valve.

The working fluid (refrigerant) at low pressure is vaporized in the evaporator by heat drawn from the dryer exhaust air. The compressor raises the enthalpy of the working fluid of the heat pump and discharges it as superheated vapor at high-pressure. Heat is removed from the working fluid and returned to the process air at the condenser. The working fluid is then throttled to the low-pressure line (using an expansion valve) and enters the evaporator to complete the cycle.

In the dryer system, hot and dry air at the exit of condenser is allowed to pass through the drying chamber where it gains latent heat from the material. The humid air at dryer exit then passes through the evaporator where condensation of moisture occurs as the air goes below dew point temperature.

A performance study of a heat pump dryer system is required to fully understand its operating characteristics based on different materials to be dried. To accomplish this objective, the project was divided into three tasks (steps). Task A is concerned with the design and construction of a prototype heat pump dryer system. Task B involves field-testing of a prototype system using specialty crops or material with similar characteristics. Finally, task C is to develop a comprehensive computer model using the fundamentals of thermodynamics for a heat pump dryer system and to determine its accuracy compared to experimental results.
