Industrial drying oven applications

Industrial drying oven applications are important in industrial production processes. They are widely used in many industries, contributing to improving production quality and efficiency.

Introducing industrial drying oven

Importance of drying process in production

The drying process plays a very important role in many industrial production industries for the following reasons:

  • Product preservation: Helps remove moisture, prevents mold and bacteria from growing, and prolongs storage time.
  • Improve quality: Improve the color, flavor, texture of the product.
  • Volume and volume reduction: Convenient for packaging, transportation and storage.
  • Preparation for the next steps: Many products need to be dried before further processing.
  • Increase product value: Products after drying often have higher value.

Industrial drying oven concept

Industrial drying ovens are specialized equipment designed to remove moisture from materials and products on a large scale in a controlled environment. Main characteristics:

  • Continuous operation with large capacity
  • Precise control of temperature, humidity, drying time
  • Use of various heat transfer methods (convection, radiation, conduction)
  • Can automate the entire process
  • Energy saving and environmentally friendly

Applications of industrial drying oven in manufacturing industries

Applications of industrial drying oven in the food industry

  • Drying fruits and vegetables: Creating dried products such as raisins, dried bananas, dried apples.
  • Drying cereals and seeds: Reduce moisture in rice, corn, beans for long-term storage.
  • Dried meat and seafood: Production of dried meat, dried fish, dried squid.
  • Drying spices and herbs: Creating dry spices such as paprika and pepper.
  • Dry milk powder and functional foods.
  • Extend shelf life: Storage life can be increased up to several months or years.
  • Maintains flavor and nutrition: Low temperature drying (40-60°C) helps preserve most nutrients.
  • Volume reduction: Up to 70-90% volume reduction is possible, saving transportation and storage costs.
  • Product diversification: Creation of new products such as dried fruit and vegetable meal.
  • Vitamin loss: Vitamin C and some B vitamins can be lost up to 50% during drying.
  • High cost: Initial investment in industrial drying systems can range from a few hundred million to several billion VND.
  • Energy consumption: On average, 1-2 kWh of electricity is consumed per kilogram of dry product.

Applications of industrial drying oven in the pharmaceutical industry

  • Drying medicinal herbs: Preserving natural herbs and medicinal herbs.
  • Drying medicine powder: Reduce moisture during the production of pills and powder medicineDisinfection drying: Sterilize medical instruments and packaging.
  • Drying of pharmaceutical additives.
  • Drying during research and development of new products.
  • Guaranteed stability: Reducing humidity below 5% helps stabilize the drug for 2-3 years.
  • Tight control: Can control temperature accurately to 0.1°C, humidity to 0.1% RH.
  • Reduce infection: High temperature drying (120-150°C) can sterilize the product.
  • High technical requirements: Need staff with in-depth training in GMP and pharmaceutical drying processes.
  • Operating costs: Can account for 10-15% of product price.
  • Active ingredient modification: Some proteins and enzymes can be denatured at temperatures above 60°C.

Applications of industrial drying oven in the wood and building materials industry

  • Wood drying: Reduce wood moisture to avoid warping and cracking after processing.
  • Dry construction materials: Bricks, tiles, cement before putting into use.
  • Drying of aggregates: Sand and gravel in concrete production.
  • Drying of insulation and soundproofing materials.
  • Drying of paints, varnishes and surface coatings in the wood industry.
  • Shorten the time: Drying wood with an oven can take only 1-2 weeks instead of a few months of natural drying.
  • Quality control: Wood moisture after drying can reach 8-12%, suitable for furniture production.
  • Reduce error rate: Can reduce the rate of warped and cracked wood to less than 5%.
  • Energy consumption: On average 2-3 kWh of electricity is required to dry 1 kg of wood.
  • Big investment: An industrial wood drying oven can cost from 500 million to several billion VND.
  • Risk of material failure: If not well controlled, it can cause cracking and breaking of bricks and tiles during the drying process.

Applications of industrial drying oven in the textile industry

  • Fiber drying: Reduces fiber moisture after spinning process.
  • Fabric drying: Stabilize fabric size after dyeing and printing process.
  • Drying during completion: Create special effects on the fabric.
  • Disinfection drying: Removes bacteria and mold on garment products.
  • Drying during the production of nonwoven fabrics.
  • Improved quality: Heat drying can increase color fastness by 20-30%.
  • Increase productivity: Shorten production time by 30-50% compared to natural drying.
  • Guaranteed hygiene: Drying at temperatures above 100°C can kill most odor-causing bacteria.
  • Effect on yarn: Drying at too high a temperature (over 180°C) can reduce the durability of cotton yarn by 10-20.
  • Operating costs: Accounts for about 5-10% of the cost of garments.
  • Skill requirements: Need trained staff on how to adjust the temperature and drying time for each type of fabric.

Benefits of industrial drying oven applications

  • Precise control of humidity, making the product more uniform and stable.
  • Minimize the risk of infection and mold.
  • Preserves many important nutritional ingredients and active ingredients.
  • Increase processing capacity, meet large-scale production needs.
  • Save storage and transportation area due to dried products.
  • Allows processing of many different types of materials on the same system.
  • Facilitate the automation of the production process.
  • Can integrate heat reuse and energy saving solutions.
  • Ensure product stability and quality according to customer and market requirements.

Factors to consider when applying industrial drying oven

Characteristics of the product to be dried

  • Initial humidity and target humidity
  • Product size and shape
  • Heat sensitivity of the product
  • Chemical and physical properties (e.g., easy to oxidize, flammable)
  • Final quality requirements (color, smell, texture)

These characteristics will determine the appropriate type of drying oven, drying temperature, drying time and treatment method.

Production scale

  • Required drying capacity (kg/hour or tons/day)
  • Continuity of production process
  • Possibility of future expansion
  • Available installation space

The scale of production directly affects the size and type of drying oven to choose, as well as the operating method (batch or continuous).
