Giving a Roast or Browned Appearance
Flash roasting is a process whereby the outside of a product is given a roast or browned appearance, without cooking the inside of the product. This can only be achieved by a short period of very intense heat. Traditional hot air ovens, even high temperature pizza ovens, cannot give the intense heat that is required in a short enough time.
Certain meat products are often steamed or cooked in a very humid atmosphere for a long period of time. This is to retain as much of the moisture that is either naturally found in the meat or is injected into the meat tissue. An example of this is ham. In the UK pork is injected with water and then cooked at a temperature of 97-98°C, either in a plastic bag or in a mould for a period of 7-8 hours. At the end of this time the meat is completely cooked and has retained most of its internal water.
There is then a need to give the product a roast look and so it has to be flash roasted. Traditionally this has always been done in a high temperature rack or deck oven. This takes from 20-30 minutes. This length of time however, is sufficient to raise the internal temperature of the meat and also to cause between 6 and 8% of the water to be released, thus reducing the yield. Framptons have developed a flash roaster specifically for this application.
A narrow stainless steel belt carries the product through a circular shaped grilling chamber, the inside of which is constructed from Frampton heating elements. These are within 50-60 mm of the outside of the product and radiate virtually all round it. It is possible with these machines to flash roast the outside of a 7Kg ham or pork or beef joint in 3 minutes. This reduces the water losses to 2% and has the added benefit that the heat penetration is in the region of 8-10mm and so the product can be packed immediately and does not have to be cooled.
These grills are also being used for roasting the outsides of chickens and also turkey saddles.
Traditional Frampton grills with normal rectangular grilling chambers can be used for flash roasting vegetables. Frampton grills are currently being used to colour potatoes and potato products that have previously been steamed cooked.
