METHOD AND APPARATUS FOR INDUSTRIAL PRODUCTION OF AN EXTRACT BY SOLID-LIQUID EXTRACTION
A method and apparatus for industrial production of an extract by solid-liquid extraction, preferably by solid-liquid hot extraction, especially for industrial scale applications and especially for production of a tea concentrate, using an extraction vessel (10; 100) according to the preamble of claim 1. It is an object of the present invention, by means of the method according to the invention and the apparatus, firstly to improve mass transfer in the course of extraction compared to solutions according to the prior art, and secondly to enable a further improvement in demoisturization of a raffinate having residual moisture in order to obtain further valuable extract. This is achieved by the method by the following method steps inter alia: (ii) intensifying the solid-liquid extraction during a first dwell time (τ1) by • at least partly purging the vessel (12; 12.1) in the form of at least one flow (S1, S2, S3) deployed in a planned and targeted manner with the secondary solvent (C) or the respective extract achieved ((C∞B)) and/or • fluidizing and suspending the primary mixture ((A∞B)) within the vessel (12; 12.1) by supplying the secondary solvent (C) or the respective extract achieved ((C∞B)) via a floor space of the vessel (12; 12.1) by means of an upward-directed fourth flow (S4) and/or • moving the vessel (12; 12.1) relative to the extraction vessel (10; 100) within the extract respectively achieved ((C∞B)); (iii) circulating the secondary solvent (C) or the extract ((C∞B)) from the top downward in the extraction vessel (10; 100) via a circulation flow incorporating the extraction vessel (10; 100), based on the extraction vessel (10; 100), and (iv) feeding the extract obtained by demoisturizing raffinate and freed of raffinate having residual moisture ((C∞B)**) into the extract ((C∞B)**) freed of raffinate having residual moisture that has already been separated or is to be separated.
The invention relates to a method for controlling the production of an extract using a solid-liquid extraction process, preferably a hot solid-liquid extraction process, in particular for large-scale industrial applications and in particular for producing a tea concentrate, using at least one extraction container (10; 100; 1000) according to the preamble of claim 1. The aim of the invention is to improve the exchange of material during the extraction process in comparison to solutions according to the prior art and to allow a controlled dehumidification of a raffinate with residual moisture in order to obtain additional valuable extracts using the method according to the invention. According to the method, this is achieved by carrying out the following steps: (i) providing the first compound (M) in the extraction container (10; 100; 1000); (ii) supplying the specified second compound (m) to the provided first compound (M) without spatial constraints and distributing and mixing the second compound into and with the first compound (M); (iii) discharging a mixture ((C∞B)+A), consisting of the extract ((C∞B)) and the raffinate (A), out of the extraction container (10; 100; 1000); (iv) separating the mixture discharged according to step (iii) into the raffinate with residual moisture (A+) and an extract ((C°°B)**) released from the raffinate with residual moisture (A+); and (v) re-treating the raffinate with residual moisture (A+) at least such that the residual moisture consisting of the extract is at least partly removed from the raffinate with residual moisture (A+) by a dehumidification process and is supplied to the already separated extract ((C∞B)).
Controlling and/or treating heat-sensitive liquid food products ensures improved control of a filling level in an infuser container. Therefore, a constant dwell time of the product to be heated is reached in the event of product-fouling in the centrifugal pump. The pump is designed such that one part of a volume flow of the product, transported by an impeller wheel, regularly rinses the impeller wheel and the areas of a pump chamber that are directly adjacent to the impeller wheel. A reduction in the volume flow of the centrifugal pump is then counteracted by increasing the initial rotational speed if the reduction is simultaneously associated with a drop in temperature of the product. The increase of the initial rotational speed is carried according to the drop in temperature of the product and/or an increase in the temperature of the steam to constantly maintain at least the temperature of the product.
