How is good quality peanut butter produced in the factories?

The large scale peanut butter factories always have whole set of peanut butter machine lines, it is for the continuous production, small peanut butter plant only has single peanut butter machine or the integrated peanut butter equipment. The operation might be different, the working principles are the same.

1.    Peanut picking: Keep peanuts that are complete, white kernel and have good flavor, filter out the ones that have gone bad, have worm problems or are not ripe.

2.    Peeling: the redskin is the impurity in peanut butter production, so it has to be removed in the pretreatment. The peanut kernels with redskin are delivered to the boiling water for 5 minutes, then they get cooled in the cold water, the redskin will shrink and is very easy to be removed, soaking time in boiling water can be adjusted but shouldn’t be too long.

3.   Washing: After the redskin is removed, wash and clean the white kernels in flowing water, deep mill the peanuts into seriflux with the milling machine.

4.    Add other ingredients: here is an example of the recipe: 30KGs of peanut seriflux, 35KGgs of White granulated sugar, 250g agar. Make sugar liquid with the concentration of about 75 percent, then add other ingredients into it, stir it well, agar can make the final product more steady.

5.    Concentration and sterilization: for the better flavor and nutritional value maintain, the concentration conditions are in the low temperature and vacuum environment, then the peanut butter is heated to 95℃ for 50 seconds and immediately into the canning process.

For peanut dehulling machine, the rubbing method, impact method and other familiar method will not be mentioned, the following are the methods currently existed only in the lab:

1. Pressure expansion method: the theory is like this, add extra air into the peanut shell first for a while, when the gas pressure in and out of the shell comes to a balance, release the pressure out of the shell in a sudden, the higher pressure gas inside of the shell will be able to broken the shell, thus the kernel and the shell are separated. The main factors are: the pressure control when adding gas; the water content of the kernel, etc.
2. Vacuum method: put the peanuts into the vacuum peanut shell removing machine, in the vacuum environment, heat the peanut to a certain temperature, with the vacuum machine working, the peanut shell temperature will rise, the water content will be steamed away, the tenacity and the hardness is lowered, as the vacuum environment creates the lower pressure, the peanut shell will be broken at certain point.
3. Laser method: use laser to cut the peanut shell one by one, the test shows that complete kernel rate can be achieved in this method, the disadvantages of high expense and low efficiency make it impossible to be promoted.

The original master peanut machine was coated with chrome giving it a shiny clean look. It was also made using a rectangle shape and the size a kitchen cabinet just slightly longer. Most of the original machines lock with keys ensuring safety of the peanuts. The machines are also heavy and moving them could require two people to carry. They have coin points since they were and are still used to vendor peanuts. They are however used in very few places they had long service and breaking into them was quite hard.

Master peanut machines come in different colors and sizes differ slightly. However those who wanted slightly bigger machines had to make direct reservations with the manufacturers. During those days it was a bit expensive to have custom made machines therefore customers had to settle with the available models available in the market. These machines are easy to operate since their size is easily set on top of a table. There are those that came with security codes to ensure you are the only one who could operate the machine.

Blanching is the process of removing the red skin that covers kernels. Regardless of the kind of peanut blanching, the kernels have to go through warm air for quite some time so as to loosen the outer skin. Thereafter, the kernels are passed through a blanching machine where huge rollers rub the kernels to peel of the skin. Next, the kernels are checked with sorters to make sure the blanching is done to the required level.

Depending with the make or design of the blanched peanut machine, one can combine their machine with other units so as to increase their capacity. Also, since the capacity of a blanching machine varies per hour, it is advisable to check the specifications on production, power consumption, and utility. If you order it directly from a supplier, make sure that it is in working order and that it meets the capacity and production requirements that you want for your enterprise. Most suppliers would be glad to help you with the technical aspect specifically installation. Therefore, you should not worry about using this machine.

An old peanut machine for sale will appear also in yard sales at quite low prices. The best thing about yard sales is that they do not have fixed prices and you could negotiate your way to a good deal.

Their prices are tailored to fit everyone’s needs. By this I mean if you are purchasing a huge machine for mass production then they have a good payment plan for you. This makes it easier for you since you can have the machine work and produce money to help pay for it. This has made them real popular and at the same time they give a warranty of service. There are other options to compare such as shipping costs and durability of the machinery and also considering you need to save some money and power.

For home use or small processing plants there are crushing machines that are used to grind and crush the peanut. They do a combination job of crushing and grinding within the same machine instead of buying separate machinery. There are many things that you should look at to compare the reason as to why you are buying the machine and the money you are intending to spend.

A good peanut crushing machine should have the capability of saving power. If you are crushing peanuts for home consumption then a machine saving power is ideal since it’s not business. If the machine is for small business then it should be able to have mass production and save you power at the same time. You should also shop around for companies that give you good offer to save you money and a warranty of service.

Very importantly look for a machine that you can use on your own without hiring help. Remember it’s for home use and you need to use it yourself. It should be convenient and also you should invest minimal amount of money to purchase peanut crushing machine.

Most of the vintage machine is used; they are normally restored so as to make them functional way. If you have a vintage machine and thinking of selling, you can restore it in a professional way so as to give it a whole new look. Repair all the damaged parts and choose a great color to paint it. If the steel part is rusty, you can re-fabricate it and then sell it for a good sum of money.
