What is Hot Air Drying Machine?
Hot air drying (HAD) is the most commonly employed commercial technique for drying vegetables and fruits, in which heat is transferred from the hot air to the product by convection, and evaporated water is transported to the air also by convection. Our Hot Air Dryers are simple systems consisting of a heater, blower, temp controller and a filter,which is in pair with a drying hopper for effective drying of food and their ingredients.
Features of Hot Air Drying Machine
Quick Drying
Hot air dryers, unlike traditional dryers, can operate in batch mode, forcing hot air through the solids. When the air circulates evenly throughout the equipment, the product is dried in one or several batches to improve the efficiency and degree of drying, especially for food dehydration.
Uniform Effect
Our hot air drying equipment utilizes forced ventilation and is equipped with adjustable air distribution panels. Most of the hot air circulates at a constant speed in the chamber and hot air system to ensure even drying of food.
Good Compatibility
This equipment is suitable for drying various food materials, including vegetables, fruits, medicinal materials, mushrooms, sea cucumbers and other materials, as well as various meats, dried fruits and other materials.
Large Capacity
The industrial hot air dryeris equipped with multi drying layer layer and fully automatic PLC programmable controller, which can quickly dry large quantities of food, ensuring its temperature and humidity.
Applications of Hot Air Drying Machine
Drying of Food
Dried slices by hot air drying oven can be applied in industrial production and meet the market's demands, and the process operations won't take long for you to learn the art of fruit drying.
Dehydration of Food Powder
Food powder is one step past food drying. After a brief processing phase, all you have to do is mill it. The dried powder can be vacuum-stored at room temperature for 6-12 months.
Dehydration of Fruit Leather
Fruit leather is a dehydrated fruit-based confectionery product, which is often consumed as snack or dessert. Fruit leathers are processed from mixing fruit puree and other additives such as sugar, pectin, acid, glucose syrup and color, and then dehydrating them into a leather-like sheet by hot air drying machine.
Types of Hot Air Drying Machine
Bin Dryers
Bin dryers are a form of batch dryer that consist of a large cylindrical or rectangular drying chamber that has a wire mesh bottom. Air is drawn into the bottom portion of the dryer and blown up through the wire mesh over the product to be dried. The walls of a bin dryer are tightly sealed to prevent heated air from escaping the drying chamber. The door to the dryer that allows fresh air in to be heated is fully opened or partially open to regulate the level of circulation of heated air in the dryer.
Tunnel Dryer
In tunnel dryers, the materials to be dried are loaded in trays attached to a trolley. The trolleys enter at one and move slowly through the drying tunnel, wherein a stream of hot air or gas is blown. The material dries as it moves through the tunnel.
Rotary Dryers
Rotary dryers consist of a slightly inclined metal cylinder with internal flights. The material is fed from the upper end of the cylinder. The agitation caused by the rotation and internal tumbling action results in rapid and uniform drying. The product is collected at the lower end of the cylinder. Rotary dryers are suitable for drying granular and non-sticky materials, for drying salts, minerals, grains, nuts, and animal feeds.
Spray Dryers
Spray drying is a quick and efficient process of directly transforming a slurry, suspension, or paste into fine dried powder form. The feed usually contains a high amount of moisture and must be transportable by a pump. It is used to produce soaps, detergents, milk, coffee, tea, salts, polymer resins, flavorings, extracts, pharmaceutical products, and others.
Components of Hot Air Drying Machine
Drying Chamber
Typically, the drying chamber is constructed of materials that will resist the shedding of particles that would otherwise contaminate the parts being dried. Most drying chamber lids do not provide a tight seal.
Blower
The blower must be able to withstand high temperatures as the return air from the drying chamber will be hot. The flow capacity of the blower should be based on the application; its temperature is the primary important factor in drying effectiveness.
Air Heater
The next major component of the basic dryer is a source of heat. The heater has sufficient capacity to raise the temperature in the dryer in a relatively short period of time but should not be so powerful that excessive cycling is required for temperature control in normal operation.
Air Exchange
Moisture in the form of humidity is created as water evaporates from the surfaces of parts being dried. A bleed-off is provided after the blower to exhaust humid air. A damper is provided to control the amount of air exhausted.
Don't Overload: Overloading is a bit of a cardinal sin when it comes to caring for your dryer. It's better to only fill it just over half way, so all kinds of food have freedom to move.
Clean the Filter: A filter clogged not only reduces drying efficiency, it puts undue stress on your dryer, and that can lead to avoidable wear and tear.
Deep Clean: You can wash the filter under the tap and use a vacuum cleaner on a low suction setting to clean out the filter housing.
Inspections: Check electrical connections, heating elements, fans, and other components to ensure they are in good working condition.
Lubrication: Some commercial food dryers may have moving parts that require lubrication. Use the recommended lubricant and follow the instructions carefully.
Calibration: For commercial food dryers that have temperature or humidity control settings, periodic calibration may be necessary to ensure accurate and consistent drying conditions.
Safety Checks: Check for any safety features such as overheating protection or emergency shut-off mechanisms and ensure they are in proper working order.
