  • Patent number: 5487605
    Abstract: A process and a device are disclosed for mixing-in liquid, pourable or lumpy substances into masses of foodstuffs, in particular foams or doughs. In order to ensure that neither the structure nor the form of the substances or of the foodstuff masses are modified during the mixing process, an elongated mixing container (1) contains at least two horizontal, spiral helices (4a, 4b) that turn in opposite directions, the diameters of which partially overlap without contact and the pitches of which are inclined in the direction of transport of the material to be mixed, so that a mixing section (4d), along which the substances can be mixed without pressure into the foodstuff mass, is formed between an input (9) and an output (3).

  • Patent number: 4597980
    Abstract: A procedure for the production preferably of food foams from flowable and pumpable mediums, as e.g. egg/white solutions, whole egg/sugar mixtures or cream products. It is applicable in the baking and confectionery industry, to the production of physically aerated baked and confectionery goods, as well as foamed confections. The main object of the invention is to produce well aerated foams of high volume with a minimum of apparatus and energy input. The invention therefore is based upon the aim of providing conditions and to introduce the gas in such a volume ratio into the medium to be foamed, that volumes of at least 900 p.c. are obtained. According to the invention, the medium to be foamed and gas are delivered separately to a pump, in a volume ratio of at least 1:8, mixed, and then the mixture (medium/gas) is delivered from the pump to a dispersion tube where it is foamed.
