Abstract
An apparatus and a method for sampling from a product flow, where the sampling is performed continuously and where the product is collected in a cup for determining physical conditions, for example, weight in relation to volume, and where the cup is emptied after ending the sampling. The apparatus is provided with at least one sampling cup provided with a filling opening and an emptying opening with different cross-sectional areas. It is not necessary to perform a turning movement of the sampling cup in order to empty it. Instead, preferably, the sampling cup is emptied by opening/uncovering the bottom. Emptying of the cup and subsequent cleaning of the cup are effected with open bottom by passage of the product flow through the cup; but, emptying may also occur in a separate duct.
Claims9
Sampling apparatus for continuous sampling from a product flow, comprising:
- at least one sampling cup positioned for being introduced directly into the product flow, having a filling opening at the top for receiving a sample and an emptying opening for emptying the cup, wherein the cross-sectional area of the filling opening is less than the cross-sectional area of the emptying opening, and
- means for moving the at least one sampling cup into and out of the product flow.
A method for sampling from a continuous product flow, comprising at least the following steps:
- introducing a sampling cup, having a filling opening the cross-sectional area of which is less than the cross-sectional area of an emptying opening of the sampling cup, into a product flow to obtain a sample by filing the cup with product from the product flow;
- withdrawing the sampling cup from the product flow, scraping the top of the sampling cup to level product filled therein and obtaining the weight of the product contained in the sampling cup;
- emptying the sampling cup by opening a bottom end of the sampling cup;
- cleaning the sampling cup with the bottom end of the sampling cup open by directing a cleaning flow through the filling and emptying openings;
- closing the bottom end of the sampling cup in preparation for obtaining another sample.
