“Processor” means any person that is engaged in the business of processing or manufacturing any farm product, that solicits, buys, contracts to buy, or otherwise takes title to, or possession or control of, any farm product from the producer of the farm product for the purpose of processing or manufacturing it and selling, reselling, or redelivering it in any dried, canned, extracted, fermented, distilled, frozen, eviscerated, or other preserved or processed form. It does not, however, include any retail merchant that has a fixed or established place of business in this state and does not sell at wholesale any farm product which is processed or manufactured by him.
