Grapes can be used for making wine, jam. grape pulp, juices, Jerry, grape seed extract, raisins, vinegar and grape seed oil. They are a source of vitamin k, copper, vitamin B and a good source of fiber. Grape pulp is unfermented but fermentable product intended for direct consumption obtained from edible portions of sound ripe grapes and can be used for various value added products.

Equipment and machines for pulp processing

These include fruit washing machine, De-stemming machine, fruit mill air crusher, transfer pump to homogenizer, air compressor, sugar syrup transfer pump and pulp packing machine.

Processing grape pulp

Step 1: consists of receiving, weighing and per-selecting fruits and thus avoiding entrant of unsuitable fruits hence improving final product quality.
Step 2: De-stemming. This consists of removal and separation of grape berries from the stem.
Step 3: Washing. This consists of cleaning fruits with water to eliminate impurities. Fruits are immersed into sodium hypochlorite solution for 15minute for period between 20-100ppm to reduce microbial load to permissible levels.
Step 4: Thermal extraction. Grapes are mixed in water  and heated  to reach 67 to 75 degrees Celsius for 2 minutes. This softens the grape skin but also the process deactivates enzymes and kill surface microorganisms.
Step 5: Pulping . Its done by helper of a pulper containing sieves with different apertures to separate peels, seeds and fiber from the pulp. Its performed consistently and rapidly because the cooling/freezing time directly influences the food pulp quality.
Step 6: Heat treatment. involves filtered pulp heat in open kettle pasteurization system. This has three stages and they include; heating, temperature maintenance with continuous steering and cooling. Pulp is heated for 10 minutes till it reaches 90 degrees Celsius. This helps in reducing mold and yeast counts.
Step 7: Filling and Packing. Pulp is filled into different types of packs  for example Carbo cans, glass bottles for longer shelf life. Its stored at room temperature for several months.
