Rotary spherical digester introduction
Rotary spherical digester is the cooking equipment used for palm oil cooking and paper pulp boiling workshop section. The operating principle is that medium enters spherical digester through quick- open cover. The palm is heated by the steam directly in the spherical digester until it is cooked and softened after a period of time. The condensate water in the sphere filter through the filter screen and under the pressure of steam in the spherical digester, it can be discharged from the drainage valve of the spherical digester.

Product Advantage:
Compared with the traditional horizontal digester, this kind of 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 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.

Structure  Description
1.This apparatus is the sphere cooking device which winds the axis whirling , and composes with spherical shell, spindle head, headstock, driving part, spraying equipment, quick open dooretc.The system of the spherical digester still needs users to prepare by oneself dredging water valve, steam escape valve, sphere steam enter valve, seal mat steam enter valve and other pipeline valve. The total construction see the spherical digester installation sketch map. 
2.Spherical shell welds with steel plate, cast steel spindle head Welding is supported on two main bearings in all ball shell both ends spheroid weight through the axle head baseboard.The axle head in the transmission side of spheroiding contains the big sprocket. Moderating the electro mechanics machine urges the big sprocket wheel to rotate through the small sprocket (offered by user).
3.The quick open door on the sphere shell.Available for feeding and pouring the material.
4.There is spraying bend tube in the spheroid, connecting through the adapter and sealing piecings in the head of stub axle. Water of condensation while cooking was discharged from here.
5.Sphere surface sliping bearing is made up of casting iron tile and axle of heart to build etc. Splendid attire oil of cylinder No. 24 (add the oil line of pure knitting wool) on the ones that stick axle neck closely on what the bearing is covered. Utilizing the siphon function of wool pours the oil into axle and tiling to form Oil film. It can guarantee the slipping bearing running well. The side of bearing has a hole available for observing.
6.The pipeline Should contain stop valve, non-return valve, safe valve, and manometer, (self-provided by users), users need to install hang climbing or support on the pipeline according to the condition of factory building.
7.The sphere shell should have the heat preservation of light quality, in order to save the energy and improve the working environment.
