Homogenizer valve

a technology of homogenizer valve and valve body, which is applied in the field of homogenizer valve, can solve the problems of increasing the speed of fat emulsion on the passage, increasing the size of the passage, and the inability to meet the needs of homogenizer valve operation, etc., and achieves low homogenization pressure, low gap height, and high capacity

Benefits of technology

The design enables efficient homogenization at varying pressures and flows, reduces wear, and is more economical, allowing for adjustable homogenization pressure and efficient cleaning, while handling larger flows than conventional valves.

Problems solved by technology

The process takes place during an extremely short period of time and what happens during this period of time is that the speed of the fat emulsion on passage increases while the pressure decreases, with the result that the liquid begins to boil.
However, it has proved that an up-scaling of existing, well functioning homogenizer valves not always functions satisfactorily in practice.
Simultaneously, the costs for such a homogenizer valve increase by several factors.
It also suffers from the drawback of wear in an uneven and uncontrollable manner, which harmfully affects the homogenization result.

Embodiment Construction

[0022]A homogenizer valve 1 according to the present invention, as illustrated in FIG. 1, consists substantially of a valve housing 2 with an inlet 3 and an outlet 4 for the liquid which is to be homogenized, as well as a plurality of valve cones 5 and a plurality of valve seats 6. The valve cones 5 and the valve seats 6 are disposed such that there occur throttles between them, homogenization gaps 7.

[0023]In the preferred embodiment, the valve seats 6 are rotational-symmetric and have a central through flow channel 8 for the liquid which is to be homogenized, constituting an extension of the inlet 3 of the homogenization valve 1. The valve seats 6 are superposed on one another and they are secured to the valve housing 2.

[0024]The valve seats 6 further display a bevel 12. The bevel 12 is turned to face towards the centre of the homogenizer valve 1. The bevel 12 is turned to face away from the inlet 3 of the homogenization valve 1. The bevel is between 20 and 45°, preferably 30° in r...

Abstract

A homogenizer valve includes two or more pressurized, movable valve cones, two or more valve seats and a valve housing which surrounds the valve cones and the valve seats. The valve cones and the valve seats are disposed so that throttles occur between them, which constitute homogenization gaps, which have a gap height h. The homogenization gaps are disposed at an angle in relation to the horizontal plane. The homogenizer valve is intended to be used in existing homogenizers and has been particularly produced to be able to obtain an efficient homogenization for liquids which are processed at a lower pressure and with a greater flow, such as, for example, pasteurized milk.

Description

[0001]This application is a continuation of U.S. application Ser. No. 12 / 864,470 filed on Sep. 8, 2010, which is a U.S. national stage application based on International Application No. PCT / SE2008 / 000688 filed on Dec. 9, 2008 and which claims priority to Swedish Application No. 0800208-1 filed on Jan. 29, 2008, the entire content of each of which is incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relates to a homogenizer valve comprising a pressurised, movable valve cone, a valve seat and a valve housing surrounding the valve cone and the valve seat, said valve cone and said valve seat being so disposed that there occurs a throttle between them, the throttle constituting a homogenization gap.BACKGROUND ART[0003]Homogenization is an industrial process which has been used for a considerable length of time, and its purpose is, in a fat emulsion such as, for example, milk, to split the largest fat globules into smaller fat globules and by such means stabilize...
