In addition, this pumpkin seed extractor is suitable for different sizes of melons. The power of it adopts the wheeled tractor power output shaft mode, which has strong dynamic flexibility and is especially applied to plain area. The machine is easy to use and maintain, safe and reliable in operation, and reasonable in performance. It is an ideal seed extract machine.

The Types of Pumpkin Seed Extractor

We have two types of pumpkin seed extract machine. First is the big size one, and its capacity is 1500kg/h. Working speed in the field can reach 2-5km/h. The second is small in size with a capacity of 500kg/h, compared with the first one, it is suitable for individual use and easy to operate and move. In the world, both types are very useful for farmers to extract seeds in the field.

The working principle of pumpkin seed extract

The pumpkin seed extract machine can be connected to a PTO-driven big tractor to work. Pumpkin picking roller brings watermelon and pumpkin into the feeding hopper while walking in the field, and then they are conveyed to the crushing chamber, which saves a lot of time and manpower. After being crushed in the chamber, the melon rind and some other impurities are discharged through the filter chambers on both sides of the seed harvester and melon pulps are separated from the screen, thereby obtaining relatively clean seeds.

Successful case

Case one

In March 2019, a customer from Ecuador ordered 2 sets of big-size pumpkin seed harvesting machines, and the whole 20GP container only can load one machine due to its big shape. The following pictures are the packing details.

Case two

This week we delivered one set of pumpkin harvester. This customer viewed our agriculture machine website, and left a comment about his contact details, saying that he wanted to buy a pumpkin seed extract. Our sales manager sent him a quotation after knowing about his situation that he has big pumpkin farmland. In the past, these pumpkins would be broken in the field, because nobody knew how to deal with them, which wastes a great number of pumpkins. But now, he needs such a pumpkin seed extract to process them so as to sell its seeds in the market.
