Introduction to Melon Seeds：

Sunflower seed is the fruit of sunflower. It can not only be used as snacks, but also as the raw material for making cakes. It is also an important raw material for extracting oil. It is a high-grade and healthy source of oil.

Melon seeds processing steps：

1.Wet seed treatment
Clean the wet melon seeds with clean water, rinse to remove impurities other than melon seeds, and then drain for use.
2.Lime soaking
Prepare the clarified lime liquid, and pour the screened melon seeds into the lime liquid for soaking. After soaking for 24 hours, take out the melon seeds, rinse them with drinking water, and remove impurities and inferior melon seeds.
3.Preparation of perfume
Weigh fennel, star anise, Zanthoxylum bungeanum, cinnamon, etc. according to the proportion and seal them into two-layer yarn bags. The yarn bags should be loose and wide to leave a gap when the spices absorb water.
4.Melon seeds pre cooked
Pour the soaked and cleaned melon seeds into the sandwich pot, the quantity is about 50 kg, and then pour in drinking water 4 times as much as melon seeds, then turn on the steam valve of the sandwich pot, boil for 1 hour, take them out, put them into the iron sieve and wash them clean.
5.Melon seeds taste good
Put 70 liters of drinking water into a mezzanine pot, add 10% salt and 1 portion of spices, then add 40 kg melon seeds, turn on the steam valve of the mezzanine pot and boil for 2 hours. At this time, you need to add water to the original volume frequently. Boiled melon seeds using spices, 1 can be boiled twice.

Melon seeds drying process：

Mix 100kg melon seeds with 5kg salt and 2kg sugar, stir well. Take clean bamboo, spread plastic woven net on it, sprinkle melon seeds evenly on it, each melon seed is about 1kg. The bamboo grates with melon seeds are sent into the curing barn and arranged on the grill.
The drying temperature of drying room is about 75 ℃ and the drying time is about 4 hours. During the drying time, the exhaust machine should be started to exhaust moisture, once every 30 minutes, 1-2 minutes each time. Finally, the seeds should be mixed with vegetable oil, 1% of the raw material. When mixing vegetable oil, the seeds should be well mixed with oil brush, and then dried.

Recommendation of Melon seeds dryer/drying machine

Commercial 100-3000kg/h large amount of dehydration wide application and easy operation

Heat pump drying machine use the principle of inverse Carnot cycle. It absorbs low-temperature heat energy in the air, which becomes high-temperature heat energy after efficient heat collection and integration by the heat pump system, and is transported to the drying room for cyclic heating and drying of materials.It refers to exhausting the hot and humid air in the drying room directly to the outside of the drying room through dehumidification device, and then replenishing natural fresh air.

Hot air circle drying machine belongs to high temperature heat pump unit. Its working principle is: the working fluid of the heat pump is compressed by the compressor, becomes high temperature and high pressure gas, enters the condenser, condenses and liquefies the heat, and is used for air heating in the drying room. The moisture in the material is vaporized and evaporated by the form of hot air, and the evaporated water vapor is discharged by the moisture discharge system, thereby achieving the purpose of drying the drying material.
