Definitions

  • the invention is based on processes for the automated cleaning of textiles or solid objects, such as dishes, using water-soluble detergents and / or cleaning agents and enzymes.
  • the invention has for its object to prevent the dissolution or inactivation of the enzymes and to avoid the rinsing of still usable enzymes.
  • a machine for machine cleaning of textiles characterized in that it comprises a tub (1) with coupled inlet for water and detergent and for the circulation of liquor by an enzyme container (6), wherein the feed of water bypassing a detergent container (2) for the first phase of the water inlet is enabled and wherein, after a certain amount of accrued water covers the bottom of the tub (1) and has already wetted the laundry, a drain pump (3) is turned on and the accumulated water, as far as it is not bound in the laundry, through a drain line (4) at the bottom of the tub (1) and a Circulation line (5) is supplied to a Enzym structurier (6), where it receives a limited amount of stored enzymes (7) and transported into the tub (1), from where it receives the laundry items together with the laundry in turn wetting liquor, said after the end of the enzyme phase by switching off the pump (3) a detergent (8) from the detergent container (2) during the opening of a valve (9) flushed by inlet from the water network (10) and via a line (11) the tub (1
  • the enzymes used can be removed from the washing process after use and reused in a later washing process.
  • the enzymes are macroscopically encapsulated by means of a washable, but water-insoluble polymer membrane. As a result, the catalytic effect can take place through the membrane without the enzymes being distributed in the washing or cleaning liquor.
  • the capsules consist of several interconnected hollow bodies, the enzyme-loaded membrane bodies are the easiest to keep out of the circulation of the liquor, for example during pumping.
  • the hollow body can be connected to cartridges and / or plates and / or tubular bodies. As a result, they become a larger unit, which can be stopped mechanically most easily in the lye flow.
  • the location is most conveniently protected by a filter against insoluble contaminants from the washing or cleaning liquor.
  • capsules or hollow bodies are advantageously filled with set to different types of pollution enzymes. It is best to use a special enzyme for every type of contamination that occurs in machine-washable or cleaning processes.
  • the ordinate O of the diagram in Fig. 1 contains unspecified scales for the amount of liquor L in the tub 1 of the washing machine in Fig. 2 , for the temperature T of the liquor and for the amounts of detergent W or enzymes E. On the abscissa A, an unspecified time scale Z is plotted.
  • the inlet of water, bypassing a detergent container 2 for the first phase of the water inlet in Fig. 1 is in Fig. 2 not shown.
  • the drain pump 3 turned on and the accumulated water, as far as it is not bound in the laundry, fed through the drain line 4 at the bottom of the tub and the circulation line 5 the Enzym representativeer 6.
  • the Enzym capableer 6 There it takes up a limited amount of the stored enzymes 7 and transports them into the tub 1, from where it receives the items of laundry together with the laundry in turn wetting lye.
  • the enzyme phase is terminated by switching off the pump 3.
  • the detergent 8 is rinsed out of the detergent container 2 during the opening of the valve 9 by inlet from the water supply network 10 and fed via line 11 to the tub 1. Then, if necessary, with further supply of water until a desired amount of liquor L and heating the liquor by means of a heater not shown up to a desired temperature T, the detergent W act on the split proteins and carbohydrates and other contaminants on the laundry items and remove them from the laundry. Later they will be together pumped with the spent liquor in a manner not shown from the tub 1 in a sewage network.
  • Enzymes 7 can be coated by innovations in process engineering (microsystems) with a thin, porous polymer membrane, which leaves the enzymes in a capsule, but allows an exchange of substances with the environment (required for the decomposition process of proteins and carbohydrates during washing).
  • Such macroscopic capsules can be bundled in containers 12 (sieve-like cartridges or crosslinking of the individual capsules with one another into larger structures such as plates, tubular bodies, etc.) in appropriate amounts for the respective process and thus retained as part of the machine in the hydraulic circuit 3 to 6 .
  • suitable filters 13 at the entrance and 14 at the exit of the enzyme container 6 may be provided upstream or the washing process should be designed accordingly.
