A device for taking powder material into liquid including an inlet to which fluidized powder is supplied with a first pressure, an outlet into a liquid tank having a second pressure less than the first pressure, a powder material intake from the inlet to the outlet, a valve for the powder material intake, and a gaseous medium intake with an outlet into the powder intake with a pressure higher than the second pressure, wherein the outlet of the gaseous medium intake is in the powder material intake downstream from the valve. A method including: applying a vacuum or low pressure to the liquid, passing powder material into the liquid through a powder material intake, providing a valve in the powder material intake, and supplying a pressurized gaseous medium into the powder material intake downstream the valve at least partially during closing and/or opening the valve.

A method of cheese production using ultrafiltrated, concentrated milk, to which is optionally added a further retentate made from ultrafiltrated milk which has been acidified with at least one starter culture to obtain a pH value of from 4.5 to 5.6. Salt and other additives are added and while supplying cheese rennet, the retentate is pumped into cheese molds or ready-made packages in which the cheese receives a final heat treatment at from 18.degree. to 65.degree. C. for a period of from 4 to 36 hours.

A centrifugal pump provided with an impeller, a pump shaft, a pump housing and with a motor coupled to the pump shaft. A shaft seal device is arranged between the pump shaft and the rear wall of the pump housing respectively, and a cooling unit mounted on the outer surface of the latter at the location where the shaft extends through a hole in the rear wall. The shaft seal device is provided with a first set of sealing element arranged between the rear wall and the pump shaft as well as with a second set of sealing element arranged so as to prevent coolant from leaking between the shaft and the cooling unit. A thrust collar is interconnected with a flush pipe extending inside the collar but around the pump shaft and further arranged under the two sets of sealing element. Coolant can flow on the inner surface as well as on the outer surface of the flush pipe. A particularly efficient seal is provided at the location in the rear wall where the extends therethrough.
摘要:
Cheese curd is produced by coagulating a milk product during its passage through a long coagulator tube under renneting conditions giving a relatively slow coagulation course. The milk product is renneted in-line and the renneted mixture is fed periodically to the inlet end of the coagulator tube during feeding periods with intermediate stand still periods, the length of a feeding period being selected so that no essential coagulation occurs in the mixture from its introduction into the coagulator tube up to the successive stand still period, and the length of a stand still period being selected so that the mixture after having been subjected to one stand still period in the coagulator tube forms a sufficiently firm coagulum to be transported by feeding new mixture during the successive feeding period towards the outlet end of the coagulator tube as a continuous plug. The speed of feeding mixture into the coagulator tube and the length of the coagulator tube are adjusted so that the residence time in the coagulator tube comprises at least one feeding period and one stand still period.
摘要:
The present invention relates to a feed composition comprising fish protein hydrolysed with a neutral and an alkaline protease. The hydrolysed fish protein may e.g. be used to replace fish meal in feed compositions to achieve a higher growth rate of the animals. The invention further relates to a method for feeding animals, e.g. fish or swine.

The invention relates to means capable of avoiding electrical current, which is being induced in the blades of a wind turbine, from being passed on to parts of the wind turbine that may be damaged or even destroyed by the electrical current. The invention benefits from the fact that the electrical current is passed along by means of electrical conductors extending from the blades and to a stationary part of the wind turbine in relation the flange of the wind turbine for mounting the hub of the wind turbine to the main shaft of the wind turbine, and where the electrical conductors lead either through or past the mounting flange of the wind turbine.

In order to reduce the requirements for cleaning and provide a structure which is also easy to disassemble for cleaning without the use of tools, a pump, which has a rotary element such as an impeller shaft, is provided with a seal which is arranged so that an annular seal element, such as an O-ring, is disposed in an annular chamber which is sufficiently elongate to allow for a small amount of reciprocal movement of the seal element therein. The movement of the seal member promotes a self-cleaning action which obviates the build-up of particulate material in the annular chamber.
