Estimating the term…
A moist non-rewetted particulate material obtained from an extract of e.g. coffee by drying, is subjected to a heat treatment being carried out without affecting the moisture content of the particulate material at a combination of temperature and time being adequate for effecting fusion so as to form a compact cake-like structure, which is disintegrated into granular material before drying to final moisture content, whereby fines may be separated without being subjected to final drying, and recirculated in the process. Hereby a product having an appearance similar to and a quality comparable to or better than that of freeze dried coffee can be obtained in a less expensive manner.
A process for the preparation of a water soluble coffee or tea product from a non-rewetted particulate material obtained from an extract by drying, wherein
A process for the preparation of a water soluble coffee or tea product from a non-rewetted particulate material obtained from an extract by drying, wherein a layer of particulate material having a substantially uniform moisture content of 4-12% by weight which is 1-10% by weight (abs.) higher than the moisture content desired in the product, is heated to a temperature of 45-120° C. in an environment substantially in moisture equilibrium with the particulate material for a period of 2-30 min. so as to form a compact cake-like structure, which is disintegrated into granular material optionally after cooling, and the granular material subjected to final drying, optionally after separation of off-size particles.
A process for the preparation of a water soluble coffee or tea product from a non-rewetted particulate material obtained from an extract by drying, wherein a layer of particulate material having a substantially uniform moisture content of 4-12% by weight which is 1-10% by weight (abs.) higher than the moisture content desired in the product, is confined between opposed endless belts being essential-ly non-pervious to gases, and heated to a temperature of 45-120° C. for a period of 2-30 min. so as to form a compact cake-like structure, which is disintegrated into granular material optionally after cooling, and the granular material subjected to final drying, optionally after separation of off-size particles.
