General Introduction of the whole line:
When we talking about tomato paste processing, we mainly means in two ways:
1. tomato puree processing line (in tomato crop season)
from fresh tomato to tomato puree
including:
fresh tomato lifting system
cleaning system, sorting system
crushing system
preheating and enzyme deactivation system
pulping and refining system
evaporation system
sterilizing system and filling system
Knowledge about making tomato puree:
Tomato paste processing facilities require a constant supply of fresh tomatoes, and it is vitally important that the tomato processing line constantly operates at maximum capacity. If capacity drops below a certain threshold, or even worse, if paste cannot be made all day every day, then production has to stop completely while all the machinery is cleaned. This can lead to a lot of wastage, both of the fresh tomatoes waiting in trucks outside, and the tomatoes in the facility in various stages of processing.
So what exactly has to happen to make tomatoes into paste? It isn't rocket science! In fact, it turns out that there hasn't been a whole lot of innovation around processing over the past four decades!
Receiving: Fresh tomatoes arrive at the plant in trucks, which are directed to the offloading area. An operator, using a special tube or boom, pipes a vast quantity of water into the truck, so that the tomatoes can flow out from the special opening at the rear of the trailer. Using water allows the tomatoes move into the collection channel without being damaged.
Sorting: More water is continuously pumped into the collection channel. This water carries the tomatoes into the roller elevator, rinses them, and conveys them to the sorting station. At the sorting station, staff remove material other than tomatoes (MOT), as well as the green, damaged and discolored tomatoes. These are placed on a reject conveyor and then collected in a storage unit to be taken away. In some facilities, the sorting process is automated
Chopping: The tomatoes suitable for processing are pumped to the chopping station where they are chopped.
Cold or Hot Break: The pulp is pre-heated to 65-75°C for Cold Break processing or to 85-95°C for Hot Break processing.
Pulp Extraction: The pulp (consisting of fiber, juice, skin and seeds) is then pumped through an extraction unit composed of a pulper and a refiner - these are essentially large sieves. Based on customer requirements, these mesh screens will allow more or less solid material to pass through, to make a coarser or smoother product, respectively.
Typically, 95% of the pulp makes it through both screens. The remaining 5%, comprised of fiber, skin and seeds, considered waste and is transported out of the facility to be sold as cattle feed.
Holding Tank: At this point the refined juice is collected in a large holding tank, which constantly feeds the evaporator.
Evaporation: Evaporation is the most energy-intensive step of the whole process - this is where the water is extracted, and the juice that is still only 5% solid becomes 12% to 16% tomato puree. The evaporator automatically regulates juice intake and finished concentrate output; the operator only has to set the Brix value on the evaporator's control panel to determine the level of concentration.
As the juice inside the evaporator passes through different stages, its concentration gradually increases until the required density is obtained in the final "finisher" stage. The entire concentration/evaporation process takes place under vacuum conditions, at temperatures significantly below 100°C.
Filling: some facilities package the finished product using aseptic bags, so that the product in the evaporator never comes into contact with air until it reaches the customer. The concentrate is sent from the evaporator directly to an aseptic tank - it is then pumped at high pressure through the aseptic sterilizer-cooler (also called a flash cooler) to the aseptic filler, where it is filled into large, pre-sterilized aseptic bags. Once packaged, the concentrate can be kept up to 24 months.
Some facilities choose to package their finished product under non-aseptic conditions. This paste must go through an additional step after packaging - it is heated to pasteurize the paste, and then kept under observation for 14 days before being released to the customer.
2.Dilution line
from tomato paste to tomato puree (out of tomato crop season)
The extraction pump - dilution tanks - sterilizing machine - can (bottle) washing machine - filling machine - capping machine - tunnel spray sterilizing machine - drying machine - printer - packing

About Us:
Our company is the first company to manufacture complete food&beverage processing line in China and we are keeping leadership position in the tomato paste processing line for 30 years since 1986 when China introduce technique from Italy/German and start to manufacture.Till now, we have set up 46 tomato processing factory in domestic and oversea market.
We has independent intellectual property rights of several equipment, including: large vacuum evaporation concentrating equipment (1000L-60000L/H), large sterilization equipment (tube and tube in tube type 1T/H-50T/H), large drying equipment (water evaporation quantity 100-10000T/H), aseptic filling equipment, and many advanced pre-treatment equipment for different fruits. Among them, the concentrated equipment for juice and jam, with its high performance and ultra-low temperature , has gained high reputation in this industry; And large tube-in-tube sterilization equipment have gain major breakthrough in energy saving, saving 30% energy compared with the industry standard, which has owned the national patent (Patent No.: ZL 201120565107.2); Various types of advanced juicing and beating equipment have been ranking first for continuous 7 years regarding their quality and sales volume.
We are the best choice for tomato sauce processing in Turnkey Solution!
