Grape drying process

How to dry grape

1: pick grape

Due to the different quality and maturity of grape, unsuitable grape should be selected before drying.

2: clean the grape

To clean the surface dust of grape, if the output is large, it is recommended to use a professional grape cleaning machine.

3: Put the grape on the tray

Spread the grape evenly on the tray with a thickness of about 5 cm, and then put them in the drying oven.

4: grape drying

Set the temperature in the drying room to 65°C and the humidity to 10%. Dry for 6~8 hours to complete the grape drying.

5: storage

The dried grape will regain moisture when they are in direct contact with the air, so a sealed package is required. If you use vacuum packaging, you can better preserve the color and aroma of grape.

Grape drying machine introduction

Working principle of grape drying machine

The grape heat pump dryer adopts the principle of reverse Carnot cycle. It absorbs low-temperature heat energy in the air, and becomes high-temperature heat energy after efficient heat collection and integration of the heat pump system, which is transported to the drying room to circulate heating and drying the grape, and the hot and humid air in the drying room is directly discharged to the outside of the drying room through the dehumidifier.

The grape heat pump dryer can quickly remove the water in the grape without affecting the original color, shape and nutrient content of the grape. The grape drying oven is equipped with a computer control system, which can realize automatic temperature control. The drying temperature range of the heat pump dryer is 20-80°C, and the materials suitable for drying are very wide, such as grains, edible fungi, medicines, seafood, bacon, fruits and vegetables, tobacco leaves, seeds, spices, etc.

 Components of grape drying machine

One set grape drying machine contains:

1:Heat pump drying host

2:Drying chamber

3:Fan frame with fan

4:Trolley with tray

The drying chamber is used 100mm polyurethane insulation board, supporting 304 stainless steel trolleys and trays.

Advantages of grape drying machine

1:High quality: grape can be maintained full of shape, bright, color.

2:Fast dehydration: 4-6 hours per batch according to different materials.

3:Wide application: a variety of materials can be dried like vegetables, fruits, herbs, meat, seafood and etc.

4:Efficient and environmentally friendly, absorb heat from the air to dry the materials, without any pollution emissions and save about 70% of operating costs compared with traditional drying technology.

5:Simple operation, easy installation or no installation.

Do you provide equipment operation training?
Yes. We can send professional engineers to the working site to guide the installation, adjustment, and operation training. All of our engineers have passports.
Now we plan to make the drying project, what should we do?
Firstly, we need to know the original moisture content of the material and after drying the final moisture content that you want to achieve. Secondly, please tell us what is your required capacity per hour or per day? Thirdly, what kind of fuel do you want to use? Coal, gas, electrical, or others. We can according to your answer recommend you the accurate drying model and design the matching heating system for your project.
What kind of drying machine is suitable for me?
We offer three types of food dryer machines: multi-layer belt drying machine, heat pump drying machine, and microwave food drying machine. Generally speaking, the multi-layer belt drying machine is more suitable for large-scale food drying, heat pump drying machine tends to be easier to operate and frequently used in the small and medium drying process, and The microwave dryer has higher drying efficiency and sterilization function. Based on your production situation, you can choose the suitable one.
