Q. What speed do the stones rotate in the electric powered mills?
A. When the mill is under a full load of grain, the speed of the stones is about 2,800 rotations per minute. In terms of the speed at the perimeter of the stones, they revolve at approximately 55km per hour.
Q. Can the SAMAP mills produce fine flour?
A. The SAMAP mill can produce very fine flour in large quantities because of its powerful motor and the particular shape and design of the precision made stones. This characteristic is handy for baking cakes, noodles, and other recipes requiring fine flour. When milling finely the bran is almost entirely broken up allowing you to take advantage of the valuable nutritional parts of the grain, which normally stay unobtainable between the layers of bran.
Q. Does milling fine flour produce more heat than milling coarse flour?
A. Yes. The finer the flour the more energy needed by the mill causing greater heat to be generated. To minimise the effects of excess heating SAMAP has patented a special feature for temperature control. This cooling system consists of two fans that work simultaneously. One fan cools the motor while a second fan, situated under the moving millstones, cools the stones. The air stream, caused by the fans, cools the stones efficiently and removes the flour from the mill chamber at the same time.
Q. Does increasing the amount of grain that goes through the mill cause even more warmth?
A. Yes. The greater the quantity of flour milled the more warmth produced in the mill. For this reason, the SAMAP grain mill has an adjustable feed inlet. This inlet allows us to mill corn, dried peas, and several other kinds of large grains at a suitable speed. The adjuster allows a very exact amount of grain to be milled at a certain time ensuring the mill is never overloaded.
Q. Why do the mills have stones for milling?
A. Stone is harder than metal and is a poor conductor of warmth in comparison to steel providing a resistance to heat. Steel rollers permit very high-speed milling but also create high temperatures. The millstones we use consist of Naxos granules and a binding agent. Naxos is an extremely hard naturally occurring stone that has long been mined for millstones. The quality of milled flour is particularly fine when milled with Naxos stones. The binding agent for these Naxos emery granules consists of stabilized magnesite cement, which has similar hardness.
Q. What is the life expectancy of the SAMAP millstones with normal family use?
A. Assuming the family makes all their flour products from the grain they mill themselves, an average family would use 180 to 225 kilograms of wheat in a year. With the proper maintenance some customers who use their SAMAP mills very intensively have already milled more than eight tons of grain without needing to renew the stones. However, when the time does arrive they are easy to replace.
Q. What sort of motor do you use in the electric powered SAMAP mills?
A. It is an industrial strength, single-phase motor with a centrifugal switch and a starting capacity of 700 watts. This drives a performance of about 1 h.p. (horse power). The motor of the SAMAP mill is completely dust tight and the cooling air does not force dust into the motor. Our motor housing is fitted with cooling flanges or fins. These armatures produce no sparks and will not cause any interference to radio or television. One of the motors important points is that it is quiet even when it is under a full load of grain.
Q. How does the Hand Mill work?
A. Because the speed of milling is limited to the strength of the person operating it, we have made the diameter of the millstones larger than the stones in the electric mill to provide a larger milling surface. As in the electric mills you are able to regulate the amount of grain being fed into the mill. The more grain fed in at a time the harder it is to mill. You can also adjust the distance between the two stones to control the fineness of the flour. These two variables make it possible for people of very different physical strength to use the mill. In order to keep the physical strength required to a minimum, we have built in double roller bearings.
Q. How do I keep my grains dry to ensure they are good enough to mill?
A. Store you grain in a container or a hessian sack in a warm dry place. Grain is very hard when it is dry. If you grain squashes then you will need to place it in a hessian sack near some warmth (but be sure not to overheat the grains) until they become hard again.
