Description

Industrial boiler washing system

The present invention relates to a washing system for a large-scale food boiler for mixing and / or preparing foodstuffs, the boiler comprising a tilting boiler section, inside which is provided a mixing shaft rotatable about its longitudinal central axis for connecting a washing tool.

Traditionally, a commercial boiler has been washed by soaking and hand brushing. This requires plenty of water and detergent. As an accessory for many boilers, a washing tool is available to assist with the washing by performing mechanical brushing using the agitator motor. An example of a washing tool is described in the previous Finnish Patent No. 106361 of the Applicant of the present application, which can save a lot of water in the washing since only 20-25% of the pot volume is needed for the actual washing. High speeds cannot be used as this will cause the water to spill out of the kettle and bring food residue with it, causing more to be washed elsewhere. At the end of the wash, the boiler is emptied and rinsed by hand, which is an additional work and still causes water consumption, though less than in traditional hand washing. In addition, 20 washing utensils must be washed separately after washing.

It is an object of the present invention to provide an improved commercial boiler washing system that can further save water and detergent and

The wash cover according to the invention is an easy-to-attach cover that prevents the water in the pot from splashing enough to operate at high speeds (e.g. 200 rpm). The washing tool is equipped with the option to use either liquid or solid detergent for cleaning the kettle.

The boiler's built-in electronics can be programmed to perform the wash function automatically.

The invention will now be further described with reference to the accompanying drawings, in which:

Figure 1 shows a known embodiment of a freestanding large-scale household boiler, and Figure 2 shows a preferred embodiment of a washing system according to the invention.

The industrial cooking boiler of Fig. 1 includes a tilting boiler part 1 (for cooking), a mixing element 2 integrated in the boiler part, to which the washing tool 20 with the brushes 3 is fixed during the washing stage. Washing with such a known washing tool is normally carried out with the boiler part 1 in an upright position (Fig. 1). In this case, typically 20-30% of its volume of water is placed in the boiler section. When washing, the rotational motion of the washing tool causes a centrifugal force to distribute the water to the edges of the kettle. The food remains 5 remain

In the washing system according to the invention, the washing operation is performed by first placing a washing tool 2 and a detergent in the boiler, for example with detergents 9 and / or directly in the boiler part. Thereafter the washing lid 7 is placed and the boiler part 1 is tilted about 90 degrees to the horizontal position 5 shown in Fig. 2 so that dirt can drain out of the boiler part through the opening 8 between the wash head 7 and the boiler part. washing water, which dissolves detergent inside the boiler section. By measuring the amount of water, for example by pulsing, the total water cost is significantly lower than using 10 standard washing tools. The water supply cycle can be, for example, 5 s water supply and 45 s pause, whereby the total water flow is 10% normal. In addition, dirty water 4 and food residues 5 can escape from the kettle via the drain opening 8. This facilitates washing and reduces the need for water and detergent.

15

At the end of the wash, the detergent no longer stands out from the detergent compartment, so rotating the washing tool and adding water will rinse the boiler so that the need for manual rinsing is minimized.

20 The system achieves approximately 50% water and detergent savings compared to a standard detergent. In addition, washing speeds up to over 50% because high speeds can be used in the washing tool to increase mechanical cleaning power. Continuous or intermittent effective rinsing and removal of food residue eliminates the need for a separate washing tool
