Today in class, we started our process for cleaning the used vegetable oil. As a class, we came up with a procedure for cleaning it. We all decided that we should first filter the oil through paint filters and then we would heat the oil to 120 degrees Celsius. After we heated the oil, we would repeat the whole process two or three more times. So, we separated into two groups, one to filter the oil and another to heat the oil. The filtering process went very quickly and the task was accomplished very efficiently. The filtering team was able to filter three buckets of vegetable oil in about 10 to 15 minutes.
Next, the vegetable oil was given to the heating team which I was in. We turned on the hot plates and started scooping the filtered vegetable oil into beakers. When all of the beakers were filled, we placed them onto the waiting hot plates. Unfortunately, the oil did not heat up to 120 degrees Celsius before the bell rang. We are going to continue tomorrow.
The things I thought that worked very well were the filtering method and the use of the hot plates. Some things that didn't work out so well were the slippery tongs and beakers because some of them were dropped. I would suggest maybe wiping the beakers and tongs down before we use them to pick up the beakers and hold stuff in them. Maybe we could get a bigger holding container in which to heat the vegetable oil so we can have larger quantities. Also, if we could have a larger heat source to heat the oil. When we filtered the oil, instead of using Styrofoam cups to scoop the oil, maybe we could use a large ladle or some device with a handle. I would suggest that because the process would be a lot cleaner and faster because the gloves people are wearing wouldn't get a whole lot of oil on them in comparison to the Styrofoam cups. We could also use that for transferring the filtered oil to the beakers.
I learned today that vegetable oil boils at 120 degrees Celsius. Also, that it will take a very long time to reach that temperature because of the density and make up of the substance. Even though we had some problems and difficulties today, I believe that today was very successful. We will learn from our mistakes and perfect them.

To be honest, I think all of your blogs are amazing and you met all of the criteria that Ms. Rioux sent in the email. I also like the suggestions you made to make cleaning the oil alot less messy and quicker. GOOD JOB!
ReplyDeleteGood Job! You explained in detail what was done, and how you accomplished what you needed to! The idea of using something bigger than the styrofoam cups is actually really good, because i thought it was taking up to much time using those small cups!!
ReplyDeleteIt looks like you guys had everything under control after you got your procedure down, but don't you think filtering, heating, then filtering again would be a little to time consuming?
