<p>Before feeding the cossettes to a main diffusion apparatus said cossettes 6 are treated on a conveyor 1 of a pre-diffusion apparatus by means of hot juice from the main diffusion apparatus, such juice being introduced at 10 to sprayers 11, passing to container 9, then line 15 to sprayers 16, thence to container 8 and pipe 19. The juice flow rate, the cossette layer height and the conveyor speed are so adjusted that the juice temperature at the outlet 19 from the pre-diffusion apparatus is 40 DEG C at the most and preferably about 30 DEG C. The cossette layer height on the pre-diffusion apparatus conveyor 1 is at least 1.5 m and preferably equal to about 2 m. <IMAGE></p> |
