Patent GB-566856-A (GB)
Title: Manufacture of potato flour products
IPC: A23L19/15
Filed: 1943-02-24
Abstract: Cooked potato mash is mixed before drying with a starch or a cereal flour to avoid, or reduce, the tendency of the mash to assume a horny character.  The starch or cerial flour is preferably dried before use.  In the case of a cereal flour having a gluten or similar protein content not sufficiently high to undergo undesirable swelling and toughening in the presence of water, e.g. rice flour, up to about 10 per cent of the weight of the mash may be added.  With cereal flour having a high content of gluten or like protein, e.g. wheat or rye flour, the amount added is increased to about 200 per cent or the potato mash is first mixed with a small proportion of a starch or flour, e.g. potato flour, having a low gluten content and then with less than 200 per cent of a cereal flour having a high gluten content.  A mixture having a loose granular form suitable for drying, is obtained by extruding the mash through a sieve directly into the starch &c. in a rotary ribbon type mixer of the Gardner type. Alternatively, a preliminary mixing may be effected in a tumbler mixer and the final mixing in a disc mill of the Bentall type. Mixing may also be effected on a vibratory screen or sieve.  Drying may be effected on trays or a travelling band dryer, in a rotary dryer, such as a Simon or Mitchell dryer, or a travelling column dryer, such as a Kestner T.V. or Rema dryer, or in a ribbon-type mixer provided with a steam jacket.  The dried material is cooled, ground and sieved.
