3673 T Analytical Mill, Seck's, as above, adapted for power 



The above mills are for analysis of coarse meal, according to the rules arranged by the Brewer's Testing 

 and Training Institute, Berlin. 



The meal turned out is identical with that used in practice. 



It can be set accurately and at will, by a scale, for any degree of fineness. 



The meal is collected direct in the mash pot. 



Readily accessible and easy to clean, hence no losses through dispersion of dust. 



It consists of a pair of rollers enclosed in a hollow-cast casing. One of the rollers has fixed bearings, while 

 the other is adjustable by means of an eccentric and a lever. The mill is worked in the ordinary way by a hand 

 crank, the revolution being transmitted from one roller to the other by spur wheels. 



The meal produced falls into a mash pot, which, with its upper rim, makes a tight joint with the inner orifice 

 of the roller casing, so that no meal dust can be dispersed through the joint. The opening in the frame casing 

 through which access is afforded to the meal chamber is closed by a door, by opening which the mechanism for 

 tightening down the joint on the rim of the pot is automatically released, so that the pot can be conveniently 

 withdrawn. 



The adjustment of the degree of fineness of the meal is effected by a hand lever which can be shifted on a 

 quadrant provided with a scale. When the index-hand of the lever stands at " o " the rollers are in contact 

 with each other, while the extreme limit of displacement is marked with the figure 50. 



In order to obtain normal meal the lever should be set up at 25. 



The apparatus can easily be dismounted, as the top part of the casing can be turned back on a hinge ; similarly 

 the cap-pieces of the bearings, which are held down by winged nuts, can easily be turned aside so that the rollers 

 can be quickly removed at any time. 



DIRECTIONS FOR USING THE LABORATORY MILL. 



FOR COARSE MEAL. 



When about to use the crushing machine, first set it for the desired degree of fineness on the scale, by means 

 of the hand lever, which should be fixed in position by tightening up the winged nuts. Then charge 50 grammes 

 of the malt to be analysed, accurately weighed out into the feed-hopper above, while adjusting the feed-slide, 

 preferably while simultaneously turning the crank by means of the thumb-screw, so that the grains can only 

 just drop through the slot between the slide and the roller. Avoid opening the slide wider than necessary, because 

 the malt will not be drawn so well into the rollers if a large quantity of malt has accumulated in the space between 

 the rollers. Then turn the crank until the whole charge of malt has passed through the rollers, after this turn 

 the mill a few times in the inverse direction in order that any particles of meal still clinging to the rollers may 

 drop off. Open the hinged doors on both sides of the rollers and clean off any adhering particles of meal from 

 the rollers by placing the brush supplied with the machine longitudinally first on one and then upon the other 

 of the roller surfaces, and pressing it gently against it while once more turning the crank. After this, clean the inner 

 slopes of the casing by passing the brush over them downwards. Now the door of the frame casing below may 

 be opened and the mash pot removed.
