Industrial fruit dehydrator machine for fruit leather making

Introduction of Industrial fruit dehydrator machine for fruit leather making

The industrial fruit dehydrator machine, as the name suggests, is used to dry fruits.  Generally, fruits have strong seasonality, and high moisture content means that fruits cannot be stored for a long time. Therefore,  industrial fruit dehydrator machine has become a popular fruit processing machine, which not only extends the shelf life of fruits, but also preserves most of the nutrients.

Features of Industrial fruit dehydrator machine for fruit leather making

1. The entire industrial fruit dehydrator machine ovenadopts a fully enclosed structure. Most of the hot air circulates in the oven. The thermal efficiency is as high as 50%, saving energy.
2. The thickness of the insulation layer is 80-200mm, and ultra-fine silicate fibrous cotton is used to further reduce thermal loss.
3. Heating source: steam (0.02-0.8MPa), electricity(3 phase electricity, voltage can be customized), hot air furnace (burning firewood, coal, oil, gas), etc. for users to choose.
4. Working temperature: Steam heating 50-140℃, and the electricity temperature of 50-350℃. The use of temperature is greater than 140℃or less than 60℃, and it is necessary to indicate when ordering.
5. Using the forced ventilation effect, the industrial fruit dehydrator machine has a adjustable division of wind plates, which can adjust the gap up and down to control the circulation of air volume, so that the material in the oven is dried uniform.
6. High -quality materials: 201/304/316 stainless steel materials are optional. The surface polishing treatment can be selected, wire drawing, mirror polished, matte surface etc.
7. Intelligent temperature control system: automatic constant temperature, automatic damp discharge, timing stop, ultra -temperature alarm, self -rectification of temperature, fixed temperature humidity PLG program control, multi -stage control, pressure monitoring, air volume monitoring, explosion -proof system.
8. Energy consumption: For reference model RT-D1, installation power 15KW, actual power consumption 5-8kw/h.
9. Batch trays standard size 460x640x45mm, can work with all the models.
10. Special requirements can be special customized.

FAQ for Industrial fruit dehydrator machine for fruit leather making

• What fruit do you dehydrate with industrial fruit dehydraor machine?

The common seen dehydrated fruits includes: banana, apple chips, strawberry, mango, pineapple, lemon, tomato, dragon fruit, fig etc. Most fruits can be dehydrated.

• How long will dehydrate fruits last?

If not specially treated, it should be full sealed and placed in a cool and dry place, shelf life usually around 6-8 months. With vacuum package. it can last half to one year.

• How to dehydrate fruits?

  

  machine for dring fruits

1.  Fruit cleaner machine
2.  Fruit peeler machine (such as mango, apple, pineapple peeling), pitting ( such as date, cherry, hawthorn pitting), coring ( such as apple, pear etc)
3.  Fruit slicing machine: cutting fruit into slice,chips, dices according to your requirement
4. Before drying,  better set the shape and color, usually apply lemon juice, or soak it in salt water
5. Spread the cut fruit on the racks evenly, push into the dehydrator machine and close the door.
6. Setting appropriate drying temperature and humidity, this is the most crucial step in the drying process of fruits and vegetables. According to different types of fruits and vegetables and drying requirements, the general drying temperature range is 50-70 degrees Celsius and the humidity range is 5-30%.
7. Cooling and storage dehydrated fruits: When the fruits and vegetables reach the desired drying level, place them in a well ventilated area for cooling. In general, the cooling time is 30 minutes to 1 hour. After the fruits and vegetables have completely cooled, place them in sealed containers or packaging bags to maintain their dry state. Choose appropriate packaging materials and ensure good sealing to prevent moisture from entering.

• Do you have to soak fruits before dehydrating?

It is not necessary. But to keep the shape and color, you can spread lemon juice or soack the fruits in salt water.

• Does dehydrating fruit remove flavor or nurtients by the industrial fruit dehydrator machine?

Fruits lose some nutrients after drying, but still have benefits

1. Partial nutrient loss after drying: nutrients such as water and water-soluble vitamins
2. Partial nutrient concentration after drying: Concentration occurs due to water loss, resulting in an increase in its concentration.
3. After drying, some minerals are not lost: mineral elements such as iron, potassium, sodium, magnesium, selenium, etc. are usually not lost, and the concentration becomes higher due to evaporation and concentration of water.

• Is a food dehydrator the same as a freeze dryer? dehydrate fruit VS freeze dry fruit

  

  freeze drying machine

  1. Shape : Freeze-drying fruits, due to their sublimation and dehydration, directly convert their moisture from the frozen state into water vapor, which has a smaller impact on the plant framework (cell wall) compared to drying. Drying will cause some shrinkage.

  2. Color: Freeze dried fruits are processed in a vacuum environment, so there are fewer oxidation reactions and a brighter color. The oxidation reaction of dried fruits is more frequent, resulting in a darker color.

  3. Nutrient retention: The full name of freeze-drying is vacuum freeze-drying machine, which freezes at temperatures above -40 degrees Celsius and undergoes sublimation and dehydration. The vacuum environment reduces the oxidation of fruits and preserves over 95% of the nutrients in the fruits. Dried fruits are produced at a temperature of 50-80 degrees Celsius, and high temperatures can cause high damage to vitamins, resulting in a higher loss rate of vitamins.

  4. Taste: The water content has decreased, and the sugar content remains basically unchanged, so compared to fresh fruits, it is sweeter and the taste is more rich.The dehydration rate of freeze-dried fruits is as high as 95%, and most of them are crispy to eat. Freeze-dried fruits have biological activity, and exposure to air can absorb moisture and soften the air. Drying mainly depends on the dehydration situation, with less dehydration resulting in softness and more dehydration resulting in crispness.

  5. Cost: The freeze dryer price is much higher than dehydrator. The running cost higherr and drying time is longer compare the dehydrator.
