1.1 This European standard specifies the safety and hygiene requirements for the design and manufacture of vegetable peelers used in the commercial and institutional catering industry, and in food shops. The machines concerned by this standard are designed to peel different sorts of vegetables and tubers such as potatoes, carrots, salsify, turnips, celery and onions. The standard is limited to machines where the maximum capacity is 50 kg. The machines are not intended to be moved during operation. The rotating plate mixes the product under appropriate conditions so that the desired operation is carried out on the entire load. This operation can be: - the abrading of the surface of the vegetable or tuber; - the cutting of fine particles of skin if the fitting is of the blade-type; - grating, an operation which is similar to abrading; - scraping or cleaning with a brush, rubber coating or cast iron surface. Machines subject to this standard use water circulation to carry waste to the waste outlet. The underside of the plate is sometimes designed with raised parts which speed up the discharge of the waste water. This European standard applies when such machines are used to operate under the intended conditions of use as defined in 3.12 of EN 292-1:1991 and stated in the instruction handbook (see 7.1), including cleaning, removal of food blockages and loading, and installation, maintenance, and disposal of wastes. Machines covered by this standard are not intended to be cleaned by high pressure water jets.
