Abstract

Steam condenser designed especially for fermenters and laboratory operations. The condenser can be easily disassembled and perfectly sanitized. There are two cylindrical vapor passage spaces around the duplicator, one for the upward direction, the other for the downward direction. Helical paths are created in the spaces to extend the flow. The lid and bottom are removable and the interior can be removed and cleaned.

Description

The invention relates to a vapor condenser for equipment requiring sterile operation, in particular for fermenters.

For vapor condensation condensers are usually used. with helical or double screw pipe.

A common disadvantage of these capacitors is the difficulty, respectively. impossible sanitation, which leads to contamination of the condensate and degradation of the processed batch.

This disadvantage is overcome by the invention comprising a hollow duplicator cylinder through which the cooling medium flows. It is an object of the invention that between the outer wall of the duplicator cylinder and the condenser jacket there is a narrower vapor passage space in which an ascending helical surface is formed, attached to the outer wall of the duplicator. The outer passage space is connected to the inner vapor passage space defined by the inner wall of the duplicator cylinder and the central tube to which the descending helical surface is attached. The vapor inlet openings are formed in the upper part and the outlet openings in the lower part of the central tube, to whose upper and lower ends the lid and the bottom of the condenser are sealed to the housing.

The capacitor according to the invention is very efficient. The condensate can either be drained or run back into the fermenter. The advantage is easy disassembly of all parts and thus easy maintenance and sanitation.

An exemplary embodiment of the invention is shown in longitudinal section in the accompanying drawing.

The capacitor comprises, in particular, a duplicator cylinder J into which the inlet J and the coolant circuit open. An outer vapor passage space 21 is formed on the outer wall of the duplicator cylinder 1, limited by the condenser sheath 2. An upward helical surface 20 is formed in the outer passageway 21 and is mounted on the outer wall of the duplicator cylinder. The housing 2, at its lower end, is detachably embedded in the bottom 2 of the capacitor and sealed by the sealing element 8.

At the upper end, the housing 2 is also detachably mounted in the condenser lid 2 and sealed by a gasket 2. An inner through space 22 is formed between the inner surface of the duplicator cylinder 1 and the central tube 2, in which the downward helical surface 19 is mounted. · Te cover 2 is an exhaust pipe J extending from the outer passageway 21. The central tube 2 'is a condenser support element and passes through openings in the center of the cover 2 and the bottom 2. · Its upper part is terminated with a female threaded socket 16 into which a screw 16 is sealed against the cover 2 by a sealing element 17.

Under the mouthpiece JO. there are outlet openings 18 for vapor supply in the central tube. In its lower part, the central tube 2 is provided with an external thread 11, into which the vapor supply fitting 12 is screwed, provided with notches for an assembly key, which is sealed outside the condenser bottom 2 by a gasket 13. 14 and 15 to drain the condensate back into the central pipe 2 ·

Instead of the descending helical surface 19 and the ascending helical surface 20, straight baffles may be used. It is also possible to install several coaxial duplicator shells.

The vapor vapors from the fermenter come through an inlet fitting 12, extend upwards through the central tube 2), open the apertures 18 in its upper part, expand and pass downward through the internal through space 22 where they are guided through the descending helical surface 19. through the outer passageway 21. Where they are guided by the ascending helical surface 20 all the way through the passages, the vapors are cooled by both the duplicator cylinder and the descending helical surface J2 and the ascending helical surface 20.

The gaseous part of the vapor vapors exits via the exhaust pipe J. The condensate collects at the bottom 2 and flows. Outlet openings JJ and JJ. back to the fermenter or may be removed by a suitable device. The cooling medium is introduced into the hollow space of the duplicator cylinder 1 through the inlet J and exits through a fitting (not shown). Axial baffles may be housed in the duplicator cylinder 1 to extend the circulation time of the cooling medium.

To clean the condenser, the screw 16 with the sealing element 17 is removed. The cover 2 with the duplicator cylinder is removed. Further, the jacket J is removed. This allows access to the descending helical surface 19 and the central tube 2.

The armature 12 is unscrewed from the central tube 2 and the bottom 8 is removed. This disassembles the condenser parts and can be easily sanitized. Installation is performed in reverse order.
