(a) Any consignee, his agent, or employee who converts to his own use goods or agricultural products entrusted to the consignee for sale or the proceeds from the sale of them is guilty of a misdemeanor and on conviction is subject to a fine not exceeding $1,000 or imprisonment not exceeding six months or both.
(b) The failure of a consignee who sells goods or agricultural products on commission to pay the proceeds from the sale, less his charges, to the person entitled to receive the proceeds within five days after receiving the proceeds from the purchaser and after demand for payment is prima facie evidence of conversion of the goods or agricultural products.
