Product Detail

Compared with the traditional horizontal digester,spherical digester has the following advantages:

With high efficiency, cooking material uniformity and less cooking time. When cooking the palm fruit, the sphere can swing intermittently, and make the palm fruit mix uniformity. So it increased the contact area with steam, reduced the cooking time and achieves uniform cooking quality.

Less labor intensity, and simple、safe operation. All the workshop section including the material filling, material discharge and cooking is in the same container, which is saved the moving time of traditional horizontal digester. And after the cooking, it avoids workers pothook and carrying in the digester. When filling and discharging, the cover is opened and closed quickly by quick-actuating cover. The start and stop of quick cover is controlled by the electrical system and equipped the safe interlocking device.

This kind of spherical digester can reduce the floor space greatly and save the investment of factory building. Because of less horizontal digester transporting journey of the material car, the floor space is only equivalent to 1/4 of the traditional horizontal digester.
