<p>A heat exchanger suitable for processing fruits, vegetables and other agricultural products and particularly tomatoes. Agricultural products to be heated are first triturated, cut, mashed or otherwise crushed and then passed through one or more product passageways in the heat exchanger. Steam is passed through one or more heating fluid passageways separated from, but in close heat exchange relationship with the product passageway. In order to attain high heat transfer from the steam to the agricultural product, the distance from the heating fluid passageway to the product in the product passageway is kept to a practical minimum. The product passageways are configured to accommodate large foreign objects such as twigs, pieces of plant, weeds and the like which are frequently included in the stream of triturated agricultural product.</p> |
