Problems solved by technology

[0010] The aforementioned disadvantages are especially felt during the washing of the platform, which has to be done regularly and with the use of large amounts of water due to the particular type of processed product and the residues deposited thereon
[0011] Although the collector is equipped with a non-return valve to drain the water, the amount of liquid collected in it prevents complete drainage, especially in washing operations, which has a negative effect on the vacuum pump

Embodiment Construction

[0022] Referring to the above-mentioned drawings, the controlled high-vacuum equipment according to the present invention, generally indicated by numeral 1, essentially consists of several parts.

[0023] At least one drying chamber 2 is provided for the product to be dried, consisting of at least one heating panel 3 and at least one enclosure 4 . The hides are placed in said drying chamber 2 to dry, said drying being carried out by its passage through a heated fluidized bed.

[0024] The working fluid will be produced from the dry product, essentially consisting of the vapors released from the hide. Preliminary condensing devices 5 are accommodated in respective platforms 3 to perform preliminary condensing, ie partial condensing, of the working fluid.

[0025] The device 1 further comprises a preliminary separating device 6 placed downstream of the preliminary condensing device 5 for separating most of the condensate contained in the working fluid which is partially condens...

Abstract

A controllable high vacuum drying apparatus comprises at least a drying chamber, an elementary condensing unit, an elementary separating mechanism, a vacuum mechanism and a return circuit along which a final dehumidifier is arranged for the system, wherein, the dehumidifier is positioned downstream the elementary separating mechanism to be separated from the vacuum mechanism in selectable and temporary manner, preferably through an isolating mechanism, residual liquid can be discharged entirely and operating fluid can be dehumidified entirely, at the same time, vacuum degree downstream the final drying mechanism in the return circuit is kept basically constant.

Description

technical field [0001] The invention can be widely applied to the field of industrial systems, and more particularly to the field of drying systems. [0002] In particular, the invention proposes a controlled high vacuum drying system especially for industrial leather, hides and similar products. Background technique [0003] It has long been recognized that the above-mentioned drying system for industrial leather, hides and similar products, according to the preamble of claim 1, comprises at least one drying chamber, a vacuum device connected to said drying chamber, a separator, all for extracting from said A header and condenser arrangement for separating condensate from vapor, and a circuit for placing the above components in liquid communication with each other; a drying chamber for the product to be dried, essentially consisting of a heating platform and a sealed enclosure. [0004] A vacuum unit is basically one or more vacuum pumps used to set and maintain the pressu...
