摘要:
Spray-dried granulates useful as washing or cleaning products or as components of such products, both for household and industrial use, contain at least 1 % by weight anionic surfactants and may have apparent densities of at least 550 g/l. These granulates may be produced by spraying slurries that contain saccharic acids or salts of saccharic acids. The use of saccharic acids or their salts at the same time lowers the viscosity of the slurries, so that more concentrated slurries may be sprayed, increasing the output of spraying towers without increasing their energy consumption.
摘要:
In a process for lubricating, cleaning and/or disinfecting conveyor belts for containers like bottles, jars, tins, bags and the like which are especially intended to contain foodstuffs, a valve is supplied with the lubricant, cleaner and/or disinfectant from a central point from one or more lubrication circuits via valves and the valves are actuated by a two-point control. The valves are controlled depending on the nature of the conveyed items, e.g. material and size of the containers, and/or on the speed of the conveyor belt. The lubricant consumption and hence the pollution of the waste water in the drawing-off region is reduced overall while full lubrication is ensured at all times.
摘要:
Described is a trolley suitable for the commercial cleaning and disinfection of floors and other surfaces. Its understructure consists of a continuous or open-worked plate (12) made entirely of plastic or a frame (3) made entirely of plastic, on which castors (4) are directly mounted. The edge of the plate (12) or frame (3) has a profile section extending round it. This decreases the susceptibility of the lower regions of the trolley to corrosion without affecting its servicability.
摘要:
A dish-washing process in industrial dish-washing machines (23) is disclosed. A detergent (2, 19) and another active substance which reinforces the detergent action are dosed into the rinsing or washing bath of the dish-washer (23). In order to durably prevent the formation of a starch deposit on the dishes washed in industrial dish-washers, a low alkaline detergent, in particular a phosphate- or NTA-based detergent, is used as a detergent (2, 19), and a detergent booster (5) containing an enzyme, preferably a carbohydrate-decomposing enzyme, in particular amylase, is used as additional active substance. It is also possible to compensate the decomposition or the degradation of the enzyme during standstill phases (11) of operation of the dish-washer by adding maintenance doses (17, 18) or intermittent doses (SD) to the washing bath before the start of a new active rinsing phase.
摘要:
A bed of particulate solids including some hydrated materials can be converted by controlled irradiation with subinfrared electromagnetic radiation into a unitary porous solid that is mechanically strong enough for easy handling. When the particulate solids include typical acid to alkaline cleaner materials, a block or tablet especially suitable for automatic cleaning machinery, with a very fast dissolution rate in water, can readily be obtained.
摘要:
According to the invention the container (2) can be substantially completely compressed; starting at the end of the container (2), shearing forces are exerted on the paste and the one container wall (10) is subsequently or simultaneously pressed against the opposite container wall (11) so that the paste is urged in the direction of the opening (4). Small, economical containers (2) can be emptied almost completely without any direct contact between the operator and the product. In addition, the packaging can be economically re-used.
摘要:
The invention concerns a floor-cleaning mop head having an oblong textile base fabric with, attached to the top at both ends, slide-in pockets for the head-holder and, attached underneath, material designed to collect moisture and dirt in the form of hair tufts, fringes, loops, foam-rubber strips, etc. The aim of the invention is to provide a disign which ensures that the pockets on top of the mop head remain open even after the mop head has been washed several times, without the other useful characteristics of the mop being affected. This is achieved by virtue of the fact that the oblong base fabric (2) consists, at least in the zone of the slide-in pockets (3), of a material which is more highly heat-shrinking than the textile material of which the pockets (3) are made.
摘要:
A fresh washing liquid tank and if required a dirty water tank are integrated in a housing (1). A suction nozzle (7) for dirty water is arranged behind the housing (1) at a fixed distance thereof, in its direction of motion. The suction nozzle (7) is connected by a suction hose (8) to a dirty water inlet of the housing (1). A dosing system (11) with a dosing and mixing device for cleaning product concentrate and water, a concentrate reservoir (12) linked to the dosing device and a water inlet (14) linked to the dosing device, is arranged between the housing (1) and the suction hose (8). The washing liquid may be accurately dosed. The time usually spent to fill the tank with the washing liquid is considerably reduced. The apparatus is compact, easy to steer, mobile and may be used without water supply and/or sewage connection.
摘要:
The invention concerns a method of water management in a counterflow washing plant with a multiplicity of chambers connected to each other in series. Washing auxiliaries are added and process water is re-used to the maximum extent in order to minimize fresh-water consumption, at least part of the rinse water being re-used as wash water. The invention also concerns an installation for feeding in and discharging water and for adding washing agents in a washing plant designed for water management by the method proposed. In particular, the invention concerns a method and installation for water management in such plants for washing textile fabrics, an agent such as peracetic acid being added as an auxiliary which liberates active oxygen to disinfect and/or bleach the fabric. The process water is re-used, without causing excess consumption, by routing it in such a way that no water containing washing auxiliaries arrives in the pre-wash zone.
摘要:
A central metering station connectable to a water pipe is used to dilute a concentrated lubricant, cleaner or disinfectant. Several distribution lines connected to the metering station lead to the points of use. At each point of use there are a mixing valve (13 - 19) connectable to the distribution line (52) and the water pipe (23) and individually adjustable for each point of use and a pressure reducer (50, 51) fitted upstream of each mixing valve. Varying concentration can be provided for each point of use (31 - 37) with little technical complexity.
